And so if the reactants basically collide more, the A value increases. So we see that enzymes predominantly affect the EA, but they can also affect A, they can decrease EA and increase A. And in both cases we basically increase the value of K. So enzymes affect the rate constant, they increase the rate constant. And so that in turn increases the rate of that reaction inside the rate law. So enzymes affect the rate constant and in turn affect the rate law. So if we take a look at the following elementary reaction in which we take A and produce B, where K is the rate constant, we see that this is our rate law.
