Question

At higher temperatures,

A) reaction rates increase because reactants move faster, collide more often, and produce more collisions with the required energy of activation.
B) reaction rates increase because reactants move slower, collide less often, and produce less collisions with the required energy of activation.
C) 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

Step-by-step explanation:

Answer 2

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

Step-by-step 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.
