16. Why does increasing the temperature affect the rate of a reaction? 1. The frequency of collisions increases, which increases the probability of a
reaction.
II. The energy of collisions increases, which causes more of the collisions to
transfer enough energy to get over the activation energy barrier.
III. The activation energy barrier is lower, which allows more reactant molecules to
get over the activation energy barrier.
