Consider a reaction A → B.
At 15.0 °C, the rate constant, k, for this reaction is 0.0639 s−1. After the addition of an enzyme (a biological catalyst), the rate constant increases to 72.1 s−1. We can define the rate enhancement of the reaction due to the presence of a catalyst as k2k1. Calculate the rate enhancement (k2k1) at 35.9 °C for the reaction due to the presence of the enzyme. Assume the pre-exponential factor (A) is not significantly affected by either temperature or the enzyme.
