Can someone explain the effect of a catalyst on rate constants?

An catalyst will lower the activation energy of a reaction. Remember from the Arrhenius expression that the rate constant depends on the activation energy, among other variables. A catalyst will affect both the rate and the rate constant for a given reaction.
