    Check what you remember

    Read the wording for your board, then hide it and explain proportion of successful collisions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.

    Reference: AQA

    At the same temperature a much larger share of colliding particles has enough energy to react, so the frequency of successful collisions rises.
