GCSE Chemistry: Energy Changes & Rates — Revision Workbook

GCSE Chemistry: Energy Changes & Rates is a five-task activity book mapped to AQA GCSE Chemistry Topics 5 and 6. Learners revise exothermic and endothermic reactions and their everyday examples, reaction (energy) profiles and activation energy, bond-energy calculations (energy in minus energy out) for higher tier, the rate of reaction (measuring gas volume and mass loss, the mean-rate formula and reading tangents and gradients), collision theory and the factors that affect rate (temperature, concentration and pressure, surface area and catalysts), and reversible reactions reaching dynamic equilibrium with a first look at Le Chatelier’s principle. Tasks 1–4 are auto-marked on screen; Task 5 is an open exam-style 6-marker. The whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
