Rate Constant & Catalysts

[blazinfury]

The rate constant in a rxn rate in based on the Arrhenius equation. In this equation, two factors can change and thus influence "k"-- temp and Ea. I was always taught that temp increases the rate if a rxn and this makes sense based on the Arrhenius eq but Ea is also a factor. Now catalysts increase the rate of a rxn by decreasing the Ea if both the fwd and rev rxn. So can we say that a catalyst influences the rate constant and thus influences the rate of a rxn by increasing the value of "k"?
