QCE ChemistryPractice Examination 10

This paper covers

• Unit 3 Chemical Equilibrium: Kc expressions and calculations, ICE tables, Le Chatelier's Principle (concentration/pressure/temperature), collision-theory mechanisms
• Unit 3 Acids: Bronsted-Lowry theory, conjugate pairs, pH/pOH, Kw, Ka/Kb, weak-acid and weak-base calculations, buffers, acid-base titration analysis and indicator selection
• Unit 3 Redox: oxidation-state assignment, half-equation balancing, galvanic vs electrolytic cells, standard electrode potentials and E°cell, spontaneity, electroplating and aluminium production
• Unit 4 Organic structure: the 12 hydrocarbon-derivative classes, IUPAC nomenclature, structural and cis-trans isomerism, intermolecular forces and physical-property trends
• Unit 4 Macromolecules: addition and condensation polymers, proteins as enzymes, carbohydrates (cellulose/starch/glucose), lipids and biodegradable polymers
• Unit 4 Synthesis: the six core reaction types, Markovnikov's rule, multi-step pathway design, esterification
• Unit 4 Industrial chemistry and green chemistry: Haber process, contact process, biodiesel and the marquee bioethanol-from-bagasse context (enzymatic hydrolysis of cellulose then fermentation), atom economy
• Stoichiometry: limiting reagent, theoretical and percentage yield throughout the bioethanol stimulus
• Assessment objectives AO1-AO4 with QCAA cognitive verbs; Band A model answers with full cause-effect chains, units, and evidence-directed evaluation
