reaction rates increase because reactants move faster, collide more often, and produce more collisions with the required energy of activation.

Explanation:

At higher temperatures, the reactant atoms gain high kinetic energy which decreases the intermolecular forces of attraction between these atoms/molecules.

Hence the rate of collision is very high which decreases the activation energy and products are formed with in a short period of time.
