In aqueous solution, the reaction of A to form B has the following rate expression:

a. Propose a mechanism that is consistent with this experi mental rate. Relate the k’s in your mechanism to k and k’.

---

b. From the pH dependence of the reaction, k’ was found to be 1.0 X 105 M-1. In a pH 4.0 buffer, it took 5 min for a 0.30 M solution of A to react to give 0.15 M B. Calculate the value of k and give its units.
