QCE ChemistryPractice Examination 1

This paper covers

• Chemical equilibrium: writing Kc expressions, calculating Kc from equilibrium concentrations and ICE tables, and interpreting the magnitude of Kc
• Le Chatelier's Principle applied to concentration, pressure, volume and temperature changes in the Haber process, with collision-theory reasoning
• Bronsted-Lowry acid-base theory, conjugate pairs, pH/pOH calculations for strong and weak acids/bases, Ka, and buffer behaviour (Henderson-Hasselbalch)
• Volumetric analysis: acid-base titration calculations including diprotic acids and concentration determination
• Oxidation states, half-equation balancing, galvanic cell EMF from standard electrode potentials, and electrolytic/Faraday quantitative calculations (aluminium, electroplating)
• Organic structure, IUPAC naming, isomerism and intermolecular forces across the twelve hydrocarbon-derivative classes
• Core organic reaction types (combustion, substitution, elimination, addition with Markovnikov's rule, oxidation, esterification) and multi-step synthesis design
• Industrial synthesis (Haber and contact processes, biodiesel, bioethanol), green-chemistry principles including atom economy, and stoichiometry with limiting reagents and percentage yield
• AO4 evaluation of economic-versus-chemical trade-offs in optimising industrial reaction conditions using evidence from stimulus data
