QCE ChemistryPractice Examination 13

This paper covers

• Unit 3: chemical equilibrium (Kc, Le Chatelier, reaction quotient) applied to esterification and industrial systems
• Unit 3: Bronsted-Lowry acid-base theory, pH/pOH, Ka, weak-acid dissociation and buffer calculations
• Unit 3: volumetric analysis - monoprotic and diprotic acid-base titrations with concordant titres
• Unit 3: oxidation states, half-equations, galvanic/electrolytic cells, standard electrode potentials and Faraday's laws
• Unit 4: organic structure, IUPAC naming, isomerism and the twelve hydrocarbon-derivative classes
• Unit 4: six core organic reactions, Markovnikov addition and multi-step synthesis design
• Unit 4: proteins and quaternary-structure denaturation - linking temperature/pH to loss of enzyme activity (food-science stimulus)
• Unit 4: industrial synthesis (Haber, contact, biodiesel, bioethanol), green chemistry, limiting reagent and percentage yield
• Assessment of AO1-AO4 only, mapped to QCAA cognitive verbs (explain, deduce, analyse, evaluate, justify) at Band A standard
