Short explanation

Explain that increasing temperature increases the proportion of particles with energy equal to or greater than activation energy. This objective belongs to Collision theory and activation energy within Rate of reaction for AQA GCSE Chemistry 8462. A strong answer should use activation energy 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.

  • Misunderstanding Activation Energy: Emphasize that increasing temperature not only increases particle speed but also increases the number of particles with sufficient energy to react, thus raising the proportion of particles with energy equal to or greater than the activation energy.
