Chemistry — Kinetics and Equilibria

Exam board: CCEA  |  Back to subjects

Board-Specific Note

CCEA specification; taken in Northern Ireland.

Learning Objectives

• Explain factors affecting rate
• Understand activation energy
• Apply Le Chatelier's principle

Key Points

• Rate ∝ concentration collisions
• Catalyst lowers activation energy
• Le Chatelier: equilibrium shifts to oppose change

Lesson Plan (50 minutes)

1. Starter (5 min): Recall prior knowledge of kinetics and equilibria with quick questions.
2. Teaching (15 min): Work through each of the learning objectives, explaining principles step by step.
3. Key points review (5 min): Revisit the key points together, confirming understanding.
4. Worked example (10 min): Model the example question: Effect of increasing temperature on equilibrium?. Solution: Shifts in the endothermic direction
5. Practice (10 min): Students attempt the practice questions independently; circulate and support.
6. Plenary (5 min): Review answers and address misconceptions.

Homework

• How does a catalyst affect equilibrium position?
• Explain why increasing concentration raises rate
• State what activation energy is

Assessment

Check practice answers against the model answer; use the built-in practice questions as formative assessment.
