Solution: An increase in the temperature of the reactants causes an increase in the rate of reaction. The best explanation for this behavior is that as the temperature increases: A. the concentration of reactants increases B the activation energy decreases.  C. the collision frequency increases.  D. the fraction of collisions with total kinetic energy > E a increases.  E. the activation energy increases.
