1Which of the following factors explains why the first ionization energy generally increases across Period 3 from sodium to chlorine?

A.The effective nuclear charge increases while the electron shielding remains relatively constant

B.The number of occupied principal energy levels increases, pulling electrons closer to the nucleus

C.The atomic radius increases across the period, increasing electrostatic attraction

D.The electron shielding effect increases substantially due to added core electrons

Explanation: Across Period 3, protons are sequentially added to the nucleus while electrons are added to the same principal valence shell (n = 3). Because the number of inner shielding core electrons (10 from neon core) remains constant, the effective nuclear charge (Zeff) increases, resulting in a stronger electrostatic pull on valence electrons and higher ionization energy.

2Boron trifluoride (BF3) has a dipole moment of zero, whereas nitrogen trifluoride (NF3) has a non-zero dipole moment. What explains this difference?

A.BF3 has a symmetrical trigonal planar geometry that cancels bond dipoles, while NF3 is trigonal pyramidal with a net dipole

B.BF3 possesses polar covalent bonds, whereas the N-F bonds in NF3 are entirely nonpolar covalent

C.Boron is more electronegative than nitrogen, preventing charge separation across the B-F bonds

D.NF3 adopts a linear geometry, which prevents bond dipole vectors from canceling out

Explanation: BF3 has three bonding pairs and no lone pairs on the central boron atom, adopting a symmetrical trigonal planar shape (120° bond angles) where individual B-F bond dipoles cancel out. In contrast, NF3 has three bonding pairs and one lone pair, producing an asymmetrical trigonal pyramidal geometry where individual N-F bond dipoles sum to a permanent net molecular dipole.

3Ethanol (CH3CH2OH) has a boiling point of 78.4 °C, whereas dimethyl ether (CH3OCH3), which has the identical molecular formula (C2H6O), boils at -24 °C. Which statement accounts for this disparity?

A.Ethanol molecules form intermolecular hydrogen bonds due to the hydroxyl group, whereas dimethyl ether molecules cannot hydrogen bond with each other

B.Dimethyl ether contains stronger London dispersion forces than ethanol because of its branched structural layout

C.Ethanol undergoes intramolecular hydrogen bonding which stabilizes its vapor phase and elevates boiling point

D.Dimethyl ether possesses ionic bonds between carbon and oxygen, making it volatile at room temperature

Explanation: Ethanol contains a hydrogen atom directly bonded to an electronegative oxygen atom (-OH group), enabling strong intermolecular hydrogen bonding between molecules. In dimethyl ether, the oxygen atom is bonded to two carbons (C-O-C) with no hydrogen directly attached to oxygen, meaning molecules interact only via weaker dipole-dipole attractions and London dispersion forces.

4Which of the following ionic compounds exhibits the greatest (most exothermic) lattice energy?

A.Magnesium oxide (MgO)

B.Sodium chloride (NaCl)

C.Calcium chloride (CaCl2)

D.Potassium bromide (KBr)

Explanation: Lattice energy is directly proportional to the product of ionic charges (|q1 × q2|) and inversely proportional to internuclear distance (|r+ + r-|). Magnesium oxide consists of divalent ions (Mg²⁺ and O²⁻, giving a charge product of 4) with small ionic radii, resulting in a substantially higher lattice energy (~3791 kJ/mol) than monovalent or larger-ion salts like NaCl, CaCl2, or KBr.

5In the propene molecule (CH3-CH=CH2), what are the hybridization states of the three carbon atoms, reading from left to right?

A.sp3, sp2, sp2

B.sp2, sp2, sp3

C.sp3, sp, sp

D.sp2, sp3, sp3

Explanation: The first carbon (CH3-) is bonded to four atoms with four single sigma bonds, giving a tetrahedral geometry and sp3 hybridization. The second (-CH=) and third (=CH2) carbons participate in a carbon-carbon double bond (one sigma bond and one pi bond), having three electron domains each, corresponding to trigonal planar geometry and sp2 hybridization.

6Consider the exothermic reversible reaction at equilibrium: N2(g) + 3H2(g) ⇌ 2NH3(g) (ΔH = -92 kJ/mol). Which change will shift the equilibrium position to the right to favor ammonia production?

A.Increasing total pressure by decreasing container volume

B.Increasing the temperature of the reaction vessel

C.Continuously removing nitrogen gas from the system

D.Adding an inert solid catalyst without changing temperature

Explanation: According to Le Chatelier's principle, increasing the pressure by compressing the system shifts the equilibrium toward the side with fewer moles of gas. Here, the reactant side has 4 moles of gas (1 N2 + 3 H2) while the product side has 2 moles of gas (2 NH3), so increasing pressure drives the forward reaction.

7For a reaction A(g) + B(g) ⇌ 2C(g), the equilibrium constant Kc = 49 at 400 K. If a reaction vessel contains [A] = 0.10 M, [B] = 0.10 M, and [C] = 1.40 M, how will the reaction proceed?

A.Qc = 196, which is greater than Kc, so the reaction will shift to the left toward reactants

B.Qc = 14, which is less than Kc, so the reaction will shift to the right toward products

C.Qc = 49, so the reaction mixture is already at dynamic chemical equilibrium

D.Qc = 1.4, which is less than Kc, so the rate of the forward reaction will increase

Explanation: The reaction quotient expression is Qc = [C]² / ([A][B]). Substituting the given concentrations: Qc = (1.40)² / (0.10 × 0.10) = 1.96 / 0.010 = 196. Because Qc (196) is greater than Kc (49), there is an excess of products relative to equilibrium, causing the reaction to shift left (reverse direction) to reach equilibrium.

8Initial rate experiments for the reaction 2NO(g) + O2(g) → 2NO2(g) show that doubling [NO] while keeping [O2] constant quadruples the reaction rate, whereas doubling [O2] while keeping [NO] constant doubles the rate. What is the overall reaction order?

A.3 (third order overall)

B.2 (second order overall)

C.1 (first order overall)

D.4 (fourth order overall)

Explanation: When doubling [NO] quadruples the rate (2^m = 4), the reaction is second order with respect to NO (m = 2). When doubling [O2] doubles the rate (2^n = 2), the reaction is first order with respect to O2 (n = 1). The rate law is Rate = k[NO]²[O2]¹, making the overall reaction order 2 + 1 = 3.

9How does adding a positive catalyst affect a chemical reaction according to collision theory?

A.It provides an alternative reaction pathway with lower activation energy, increasing the fraction of effective collisions

B.It increases the average kinetic energy of the reacting particles without altering the activation energy barrier

C.It makes the overall enthalpy change (ΔH) of the reaction significantly more negative

D.It increases the total number of molecular collisions per second by raising the system temperature

Explanation: A catalyst provides an alternative mechanistic pathway with a lower activation energy (Ea). According to the Maxwell-Boltzmann distribution, lowering Ea means a significantly larger fraction of molecular collisions possess kinetic energy equal to or greater than the new activation energy threshold, thereby accelerating the reaction rate.

10What is the correct equilibrium constant expression (Kc) for the thermal decomposition of calcium carbonate: CaCO3(s) ⇌ CaO(s) + CO2(g)?

A.Kc = [CO2]

B.Kc = [CaO][CO2] / [CaCO3]

C.Kc = [CaO] / [CaCO3]

D.Kc = [CaCO3] / ([CaO][CO2])

Explanation: In heterogeneous chemical equilibria, pure solids and pure liquids have constant concentrations (densities) and thermodynamic activities equal to 1. Therefore, CaCO3(s) and CaO(s) are omitted from the equilibrium expression, leaving Kc = [CO2].

About the Tawjihi Health Field Exam

The General Secondary Education Certificate Examination (Tawjihi) Health Field (الحقل الصحي) is the primary pre-university examination in Jordan for students seeking admission into medical school, dentistry, pharmacy, nursing, and allied health sciences. As part of the four academic fields established in the Ministry of Education's 2026 comprehensive reform, the Health Field places rigorous focus on Chemistry, Biology (Life Sciences), Advanced English, and an applied scientific elective. Important Notice: The official Tawjihi examination is delivered in Arabic (with English evaluated as Advanced English). This practice question bank is an independent English-language MCQ study adaptation authored by OpenExamPrep for conceptual review and mastery — it is not an official translation, not an approved or endorsed Ministry resource, and not a simulation of the exam's native Arabic testing environment.

Exam sponsor: Examinations and Tests Directorate, Jordan Ministry of Education. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Under Jordan's reformed two-year secondary education model, whose first cohort graduated in the 2026 sitting and which the Education Council reduced to four academic fields from 2026/2027, the cumulative Tawjihi score comprises Grade 11 common ministerial subjects (accounting for 30%) and Grade 12 field-specific ministerial examinations (accounting for 70%). The Health Field (الحقل الصحي) requires four ministerial Grade 12 subjects: Chemistry, Biology (Life Sciences), Advanced English, and one elective chosen from Physics, Mathematics, or Earth and Environmental Sciences. Each ministerial examination paper contains 50 multiple-choice questions administered electronically. The four Grade 12 ministerial subjects are equally weighted, each carrying 17.5% of the final average (a maximum mark of 175 out of 1000); the Ministry does not publish a differential weighting between them, so the subject emphasis of this practice bank is an OpenExamPrep study-design choice rather than an official blueprint.
