IGCSE Chemistry Notes on Chemical Energetics
6.1 Energetics of a reaction
Core
- Describe the meaning of exothermic and endothermic reactions
- Interpret energy level diagrams showing exothermic and endothermic reactions
Supplement
- Describe bond breaking as an endothermic process and bond forming as an exothermic process
- Draw and label energy level diagrams for exothermic and endothermic reactions using data provided
