QCE ChemistryPractice Examination 7

This paper covers

• Unit 3 redox: standard reduction potentials, galvanic cell EMF, spontaneity and reducing-agent strength (galvanic-corrosion / sacrificial-anode context)
• Unit 3 redox: oxidation-state assignment, half-equation balancing, electrolytic cells and Faraday's law
• Unit 3 equilibrium: Kc expressions and calculations, ICE tables, Le Chatelier's Principle (concentration/pressure/temperature)
• Unit 3 acids/bases: pH/pOH, strong vs weak acids/bases, Ka/Kb, buffers, Kw temperature dependence, volumetric and back-titration analysis
• Unit 4 organic: structure, naming, isomerism and IMF-based physical properties across the 12 hydrocarbon-derivative classes
• Unit 4 organic reactions: combustion, nucleophilic substitution, elimination, addition (Markovnikov), oxidation, esterification and multi-step synthesis
• Unit 4 synthesis/design: Haber and contact processes, biodiesel/bioethanol, green-chemistry principles, limiting reagent and percentage yield
• AO1-AO4 cognition coverage with QCAA cognitive verbs (explain, calculate, deduce, determine, analyse, compare, evaluate, justify) and Band A evidence-directed reasoning
