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

D reaction rates decrease because reactants move slower, collide more often, and produce more collisions with the required energy of activation.

Answer 1

A — reaction rates increase because reactants move faster, collide more often, and a larger fraction of collisions have the required activation energy.
