This downloadable PowerPoint (.pptx) is a complete teaching and revision tool for the Chemical Energetics topic, aligned with the IGCSE and KS4 Chemistry curriculum. It covers essential concepts including exothermic and endothermic reactions, enthalpy change (ΔH), energy profile diagrams, bond energy calculations, and activation energy.
The lesson begins with an interactive starter activity on instant hot and cold packs, followed by step-by-step notes and class tasks to help students understand energy changes during chemical reactions. Learners will practise calculating enthalpy changes using bond energy values and interpreting chemical equations in real-world contexts like combustion and decomposition.
This resource is ideal for whole-class instruction, student revision, homework, or flipped learning environments.
