Catalysts

Does the presence of a catalyst change the value of rate constants?

A catalyst decreases the activation energy of a reaction. The Arrhenius equation includes both the activation energy and the rate constant. It shows that an increase in the activation energy would lead to an increase in the rate constant.

If you compare the graphs of a reaction with and without the catalyst, it will show that the reaction with a catalyst didn't have to input as much energy to continue.
