dependent upon the overall order of the reaction The units for a rate constant, k, are: dependent upon the overall order of the reaction a rate constant is unitless M^-1 M^-1 s^-1 s^-1 the fraction of collisions with total kinetic energy greater than Ea increases. 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, the collision frequency increases. the fraction of coll...
