Check what you remember
Read the wording for your board, then hide it and explain successful collisions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The same fixed proportion of collisions has energy greater than or equal to Eₐ, so these become more frequent and the rate rises.
Collisions in which particles have at least the activation energy and the correct orientation, so that a reaction occurs.
Collisions that produce a reaction, which rate depends on the frequency of rather than the total collision frequency.
A higher frequency of successful collisions increases the rate of reaction.
