Check what you remember
Read the wording for your board, then hide it and explain temperature and rate in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Raising the temperature broadens the distribution and increases the number of molecules beyond the activation energy, so more successful collisions occur per second and the rate rises.
Raising the temperature makes a reaction faster, and usually much faster, with a plot of rate against temperature being a curve that steepens.
