Question

According to the collision theory, what is the best explanation for why a higher temperature makes a reaction go faster?

There are fewer collisions per minute.
It increases the distance between the particles.
It decreases the average kinetic energy of the particles.
It increases the average kinetic energy and number of collisions per minute.

Answer 1

A higher temperature makes the particles move faster, that makes them collide more often. The answer would be this: "It increases the average kinetic energy and number of collisions per minute."
