Energy Changes and Reversible Reactions

Analyse the energy transfers in reversible reactions, noting the relationship between the forward and reverse directions.

National Curriculum Attainment TargetsDfE National Curriculum (England) / GCSE specifications Combined Science Key Stage 4: Chemistry - The rate and extent of chemical change;Explain that if a reversible reaction is exothermic in one direction, it is endothermic in the opposite direction.

About This Topic

Analyse the energy transfers in reversible reactions, noting the relationship between the forward and reverse directions.

Key Questions

  1. If a forward reaction is exothermic, what can be said about the reverse reaction?
  2. How does the amount of energy transferred in the forward reaction compare to the reverse reaction?
  3. Explain how heating or cooling a reversible reaction affects the yield of products.

Planning templates for Combined Science

Lesson Plan

5E Model

The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.

Unit Planner

Thematic Unit

Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.

Rubric

Single-Point Rubric

Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
