QCE ChemistryPractice Examination 5

This paper covers

• QCAA Chemistry Units 3 & 4 External Assessment (50% of subject result), simulated across Paper 1 (Section A: 20 MC + Section B: 8 short-response, 38 marks) and Paper 2 (Section C: 8 short/extended-response, 52 marks) for a grand total of 110 marks
• Unit 3 Topic 2 redox and electrochemistry anchored on the stimulus context: silver electroplating of a copper bracelet in a AgNO3 electrolytic cell - half-equations, anode/cathode identification, ion movement, Faraday's-law mass calculations, E°cell, and galvanic vs electrolytic distinction
• Unit 3 Topic 1 chemical equilibrium: Kc expressions and calculations, ICE tables, Le Chatelier's Principle (concentration/pressure/temperature) explained through collision theory
• Unit 3 Topic 1 acids and bases: Bronsted-Lowry theory, conjugate pairs, pH/pOH, Ka/Kb weak-acid calculations, buffers, and acid-base volumetric titration analysis with curves and indicator selection
• Unit 4 Topic 1 organic structure: the 12 hydrocarbon-derivative functional-group classes, IUPAC nomenclature, structural and cis-trans isomerism, and intermolecular-force explanations of physical-property trends; macromolecules (addition/condensation polymers, proteins, carbohydrates, lipids)
• Unit 4 Topic 2 synthesis and design: the six core reaction types (combustion, nucleophilic substitution, elimination, addition with Markovnikov's rule, oxidation, esterification), multi-step pathway design, industrial processes (Haber, contact, biodiesel, bioethanol), green-chemistry atom economy, and stoichiometry (limiting reagent, percentage yield)
• Assessment Objectives AO1 (describe/explain), AO2 (apply/calculate/deduce), AO3 (analyse/compare), AO4 (interpret/evaluate/justify) with Band A model answers, fully worked arithmetically-verified calculations, and QCAA-style marking-guide criteria reflecting cognitive-verb precision

Students are permitted to bring into the examination the materials normally allowed for this subject. Answer all questions in the spaces provided.
