Question
Explain how reversible reaction supports this AQA GCSE Chemistry objective: explain that if one direction of a reversible reaction is exothermic, the opposite direction is endothermic.
Answer
A strong answer should state the relevant chemistry idea, explain how it applies in Energy changes and reversible reactions, and finish by linking back to Reversible reactions and dynamic equilibrium.
Explanation
This answer is correct because it directly supports the approved learning objective: Explain that if one direction of a reversible reaction is exothermic, the opposite direction is endothermic. It stays inside Energy changes and reversible reactions, uses reversible reaction as the revision focus, and gives the Chemistry reasoning needed for an exam-style response.
Common mistake
Confusing Exothermic and Endothermic
Students often confuse which direction of a reversible reaction is exothermic and which is endothermic.
To fix this, remember that if the forward reaction releases energy (exothermic), the reverse reaction must absorb energy (endothermic), and vice versa.
