according to the collision theory and model created to explain the collision theory, what is the best explanation for why a higher concentration makes a reaction go faster?
there are more collisions per minute.
it increases the distance between the particles.
it increases the average kinetic energy of the particles.
it increases the average kinetic energy and there are more collision per minute.
