Complete Topic 3c: Equilibrium Edexcel IGCSE Chemistry 9–1 Bundle 3 lessons

Bundle of 3 fully planned lessons and resources for Topic 3c Equilibrium Edexcel IGCSE 9–1 Double/Separate Chemistry.

Checklist, tech guide, revision PowerPoint, coursebook questions and answers included. Perfect for new and experienced teachers, this resource provides an authentic, ready-to-teach unit requiring no additional preparation. All lessons are contained in one PowerPoint with a consistent, clear structure.

Lessons & Key Content:

1. Reversible Reactions – identifying reversible reactions, dehydration/rehydration of copper(II) sulfate, decomposition of ammonium chloride, recognising endothermic and exothermic directions.

2. Dynamic Equilibrium & Pressure – conditions for equilibrium (closed system, constant concentrations, equal forward/reverse rates); modelling equilibrium; predicting shifts using changes in pressure, with examples such as NO₂ ⇌ N₂O₄ and the Haber process.

3. Temperature & Equilibrium – determining whether the forward reaction is endothermic/exothermic from ΔH values; predicting equilibrium shifts using temperature changes; demonstration using cobalt chloride colour changes; extended worked examples.

4. Catalysts & Equilibrium – understanding that catalysts do not shift equilibrium but increase the rate of both forward and reverse reactions equally.

5. Revision & Practice – structured questions, diagrams, and exam-style equilibrium problems.

Each lesson includes starter slides with title, learning goals and tasks, along with key terms, bolded explanations, and content checked against the specification and examination papers. Key demonstrations are included where relevant with step-by-step modelling, notes, diagrams and student tasks and quizzes. The PowerPoint features click-in animations, embedded video links, model questions and answers, and coursebook tasks to support strong conceptual understanding. Plenaries link back to learning goals. A technician guide and full lesson list appear on Slide 2 for easy planning.

Notes:
Slide 1 is repeated for TES display purposes.
Lesson starter slide background is black but PowerPoint colour schemes vary throughout.
Separate Chemistry content is clearly marked and distinguished from Double Award content.
