For the reaction 2A + B → products a friend proposes the following mechanism:
A + B ⇌ M
A + M → products
a. Assuming that the second step is the rate-determining step and the first step is a fast equilibrium step, deter-mine the rate law. Represent the rate constant in terms of k1, k–1, and k2.
b. Using the steady- state approximation, determine the rate law.
c. Under what conditions of [A] and [B] do you get the same rate law in parts a and b?
