Sample PEC EPE Chemical Practice Questions

Try these sample questions to review concepts for the PEC EPE Chemical exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Evaluate ∫₀¹ (4x³ − 2x) dx.
A.0
B.1
C.2
D.−1
Explanation: ∫₀¹ (4x³ − 2x) dx = [x⁴ − x²]₀¹ = (1 − 1) − 0 = 0.
2For matrix A = [[2, 1], [0, 3]], what is det(A)?
A.5
B.6
C.2
D.3
Explanation: det([[2,1],[0,3]]) = 2×3 − 1×0 = 6.
3A process yield sample (n = 5) is 78, 80, 82, 84, 86%. Sample mean and sample standard deviation (n−1) are:
A.82%; 3.16%
B.82%; 2.83%
C.80%; 3.16%
D.82%; 4.00%
Explanation: Mean = 82. Deviations: −4,−2,0,2,4; sum of squares = 40; s² = 40/4 = 10; s ≈ 3.16%.
4If Laplace transform L{f} = 1/(s+2), then f(t) for t ≥ 0 is:
A.e^{−2t}
B.e^{2t}
C.2e^{−t}
D.δ(t) − 2e^{−2t}
Explanation: L{e^{−at}} = 1/(s+a). Here a = 2, so f(t) = e^{−2t}.
5In the reaction Zn + Cu²⁺ → Zn²⁺ + Cu, zinc is:
A.Oxidized (loses electrons)
B.Reduced (gains electrons)
C.Neither oxidized nor reduced
D.A spectator ion
Explanation: Zn goes from 0 to +2 oxidation state, losing electrons—oxidation. Cu²⁺ is reduced.
6For a weak acid HA with Ka = 1.0×10⁻⁵ and C = 0.10 M, approximate [H⁺] is:
A.1.0×10⁻³ M
B.1.0×10⁻⁵ M
C.1.0×10⁻² M
D.1.0×10⁻⁶ M
Explanation: [H⁺] ≈ √(Ka C) = √(1.0×10⁻⁶) = 1.0×10⁻³ M for dilute weak acid approximation.
7The pH of 0.010 M strong acid HCl (complete dissociation) is:
A.2.0
B.1.0
C.12.0
D.0.01
Explanation: [H⁺] = 0.010 M → pH = −log(0.010) = 2.0.
8At equilibrium for N₂ + 3H₂ ⇌ 2NH₃, increasing pressure at constant T (ideal gases) shifts equilibrium:
A.Toward NH₃ (fewer moles)
B.Toward N₂/H₂ (more moles)
C.No shift for any gas reaction
D.Always to the left regardless of stoichiometry
Explanation: Le Chatelier: higher P favors the side with fewer gas moles (2 vs 4).
9Oxidation number of Cr in Cr₂O₇²⁻ is:
A.+6
B.+3
C.+7
D.+12
Explanation: 2x + 7(−2) = −2 → 2x − 14 = −2 → 2x = 12 → x = +6.
10A 50 N force acts at 30° to the horizontal. The horizontal component is:
A.25√3 N
B.25 N
C.50 N
D.50√3 N
Explanation: Fx = 50 cos 30° = 50 × (√3/2) = 25√3 N ≈ 43.3 N.

About the PEC EPE Chemical Exam

The Engineering Practice Examination (EPE) Part-II for Chemical & Polymer Engineering is PEC’s discipline paper for Registered Engineers seeking Professional Engineer (PE) registration. It is a 3-hour open-book MCQ paper with 60 questions: 25 Breadth items aligned to the undergraduate chemical/polymer curriculum (math, chemistry, mechanics, balances, thermo, fluids, heat/mass transfer, control, transport) and 35 Depth items spanning common plant topics (heat/mass transfer, reaction engineering, plant design/safety) plus one opted specialization (e.g., Process Design & Optimization, Separation, Polymer, Utilities, Instrumentation & Control, Thermal Hydraulics, Environment/Process Safety themes, Energy, Corrosion). Candidates must also pass Part-I (common, 40 MCQs, 2 hours) at 60% independently.

Exam sponsor: Pakistan Engineering Council (PEC) / EPDC. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

PEC EPE Chemical: Suggested Study Strategy

1Map Breadth hours to syllabus weights (fluids/heat/mass ~10% each; balances 8%; control 9%; chemistry 10%)
2Choose a Depth track that matches your daily practice (e.g., Separation for process plants or Polymer for plastics plants)
3Build a tabbed open-book kit early—Part-II rewards fast lookups of steam tables, LMTD charts, and design correlations
4Practice timed 60-question sets in three hours to match Part-II pacing
5Drill material/energy balances and reactor sizing—these recur in both Breadth and Depth
6Keep Part-I (management, ethics, environment, hazards, communication) warm if attempting both parts the same day
7Confirm cycle dates, centres, and fee voucher rules on cpd.pec.org.pk before applying
8Only bring a simple calculator—programmable devices and phones are prohibited

Frequently Asked Questions

How many questions are on PEC EPE Chemical Part-II?

Part-II Chemical & Polymer has 60 multiple-choice questions: 25 Breadth (Section A) plus 35 Depth in your opted specialization (Section B). The paper lasts three hours and is open-book for bound books and standards only.

What is the passing score for EPE Part-II?

You must score at least 60% in Part-II. Part-I and Part-II are passed independently; failing one part does not cancel a pass in the other within the allowed retake window.

What Depth specializations can Chemical & Polymer candidates opt?

Per the official Chemical & Polymer syllabus, Depth covers common plant themes (heat/mass transfer, reaction engineering, plant design/safety) plus opted areas such as Process Synthesis/Design & Optimization, Operation & Production, Utilities & Services, Environment & Process Safety themes, Instrumentation & Control, Thermal Hydraulics, Polymer Engineering, Biochemical Engineering, Energy Engineering, Separation Process Engineering, and Corrosion Engineering. Attempt only the Depth area you select.

Who is eligible to sit for the EPE?

A PEC Registered Engineer with at least five years of relevant practical experience since registration (to the announcement closing date) and at least 17 CPD credit points since 10 July 2010 or initial registration, whichever is later.

Is Part-II open book?

Yes. Part-II allows books and bound copies of standards/texts as described for the discipline. Loose notes, handouts, and electronic devices (except a simple calculator) are not permitted.

How is the EPE fee paid?

Fees are published on each cycle’s notice. Payment must be made through a Bank Alfalah system-generated voucher from the CPD portal; deposits by other methods are not accepted. Always confirm the current amount before paying.
