Question:

The pre-equilibrium and the steady-state approximations are two different approaches to deriving a rate law from a proposed mechanism. For the following mechanism, determine the rate law

(a) By the pre-equilibrium approximation and

(b) By the steady-state approximation.

(c) Under what conditions do the two methods give the same answer?

(d) What will the rate laws become at high concentrations of Br^–? CH3OH + H ; CH3OH+ + CH3OH + Br (fast equilibrium) CH3Br + HO (slow)
