Achieve #20

[Maritza Jacobo]

For question 20, how do you determine the catalyzed reaction at the reaction rate that's given? I know you need e^ but I'm not sure how to set it up. Thank you in advance!

So k = Ae^((-Ea)/RT). You would plug in the values of Ea, R and T in into this. Since the question is asking k(cat)/k(uncat), you can set up two equations for k and divide them by each other. This way, the A cancels out and you're able to obtain the factor (k(cat)/k(uncat).

The pre‑exponential factor A, is the same in both the catalyzed and uncatalyzed reactions, it cancels out
And since e^{x}/e^{y}=e^{x−y}
