Question

How does temperature affect the rate of a reaction?

A. Increasing the temperature decreases the potential energy of the
reactants.
B. Increasing the temperature gives the molecules more kigetic
energy
C. Increasing the tek perature increases the concentration of the
reactants
D. increasing the per perature lowers the activation energy of the
reaction

Answer 1

B, more kinetic energy means more collisions and thus more reactions according to collision theory.
