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.

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