This lesson covers AQA Trilogy Combined Science specifications 5.6.2.5 and 5.6.2.7 and develops understanding of how reversible reactions respond to changing conditions.

Students will:

• Recall what a reversible reaction is and explain how dynamic equilibrium is reached in a closed system
• Predict how changes in concentration and pressure affect the position of equilibrium using Le Chatelier’s principle

The lesson includes retrieval quizzes, structured activities, and exam-style questions, suitable for KS4 higher-tier teaching or revision.
