Part of the AQA GCSE Combined Science curriculum.
AQA GCSE Combined Science 5.6 Rate and Extent of Chemical Change is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the AQA specification (AQA GCSE Combined Science: Trilogy (8464) – 5.6 Rate and extent of chemical change). It covers measuring the rate of a reaction, rate graphs and tangents, collision theory and factors affecting rate, required practical 11 – concentration and rate, catalysts, reversible reactions and equilibrium and changing the position of equilibrium, then brings it all together with mixed retrieval and exam practice.
There are 23 short steps of about 15 minutes (roughly 6 hours of learning), each made of bite-size explanations with key words, tables and examples, and every bite-size is followed by an activity you check straight away. Key terms include Rate of reaction, Mean rate, Rate curve, Tangent, Collision theory, Activation energy, Required practical 11, Independent variable, Catalyst, Enzyme, Reversible reaction and Closed system.
