Short explanation

Explain that if one direction of a reversible reaction is exothermic, the opposite direction is endothermic. This objective belongs to Energy changes and reversible reactions within Reversible reactions and dynamic equilibrium for AQA GCSE Chemistry 8462. A strong answer should use endothermic accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.

  • Confusing Exothermic and Endothermic: To fix this, remember that if the forward reaction releases energy (exothermic), the reverse reaction must absorb energy (endothermic), and vice versa.
