Part of the Eduqas GCSE Combined Science curriculum.
Eduqas GCSE Combined Science Topics 8–9 Energy, Rates and Equilibrium is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the Eduqas specification (Eduqas GCSE (9–1) Combined Science (C430) – Concepts in Chemistry, Topics 8–9: Energy changes in chemistry; Rate of chemical change and dynamic equilibrium). It covers exothermic and endothermic reactions, reaction profiles and activation energy, bond energies, measuring rates of reaction, collision theory and rate factors, catalysts and enzymes and reversible reactions and dynamic 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 Exothermic, Endothermic, Activation energy, Reaction profile, Bond breaking, Bond making, Rate of reaction, Mean rate, Collision theory, Collision frequency, Catalyst and Alternative pathway.
