Question

Why does raising temperature generally increase the rate of a chemical reaction? a It causes particles to become lighter and more likely to change form. b It causes particles to skip the transition state before forming products. c It causes particles to move more slowly so they can stick together. d It causes particles to collide more often and with more kinetic energy.

Answer 1

d. It causes particles to collide more often and with more kinetic energy.

Answer 2

The particles have more kinetic energy, move faster, thus collide more often and can also get over energy barriers more frequently.
