Short explanation

Explain that increasing concentration increases collision frequency in solutions. This objective belongs to Collision theory and activation energy within Rate of reaction for AQA GCSE Chemistry 8462. A strong answer should use concentration 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.
