This lesson covers AQA Trilogy Combined Science specifications 5.6.2.1–5.6.2.3 and introduces reversible reactions, energy changes, and the concept of equilibrium.
Students will:
- Define what a reversible reaction is
- Recall endothermic and exothermic reactions
- Understand that bond making releases energy and bond breaking requires energy
- Describe and explain that if a reversible reaction is exothermic in one direction, it is endothermic in the opposite direction, with equal energy changes
The lesson includes retrieval quizzes, structured activities, and exam-style questions, making it suitable for KS4 classroom teaching or revision.
