QCE ChemistryPractice Examination 16

This paper covers

• Chemical equilibrium: Kc expressions, ICE tables and Le Chatelier applied to the contact process (SO2 oxidation over V2O5) as a yield-vs-rate compromise
• Bronsted-Lowry acid-base theory: pH/pOH, strong vs weak acids/bases, Ka/Kb, buffers and acid-base titration stoichiometry
• Oxidation-reduction: oxidation states, half-equations, galvanic cell EMF from standard electrode potentials, and electrolysis (Faraday's laws, electroplating, aluminium)
• Organic chemistry: hydrocarbon-derivative structure/naming/isomerism, IMF and physical properties, and the six core reaction types including Markovnikov addition and esterification
• Industrial synthesis and green chemistry: contact process, Haber process, biodiesel/bioethanol, percentage yield, limiting reagent and atom economy
• AO1-AO4 cognition: explain (causal chains via collision theory), apply/calculate (formula-substitution-units), analyse (trends/limitations in stimulus data), and evaluate/justify (weighing yield-rate-cost trade-offs against stated evidence)
