Distinguish collision frequency from collision energy when explaining rate changes.

In Collision theory and activation energy, this learning objective focuses on how to distinguish collision frequency from collision energy when explaining rate changes. Within Rate of reaction, students should keep the idea anchored to Collision theory and activation energy rather than drifting into a different rate, equilibrium, catalyst, reversible reaction, or graph concept. Key terms to use include distinguish, collision, frequency, from. A strong AQA GCSE Chemistry answer names the exact factor or relationship, explains the particle or equilibrium reason where needed, and links the point back to the question wording with correct units or graph language when relevant.
