Problem 1 (25 points). Wilkinson's catalyst is a homogeneous organometallic olefin hydrogenation catalyst. Its mechanism is shown below with A,AP,B,BO, and C to represent the catalytic intermediates. Assume the catalyst concentration is much lower than the reactant concentration. Assume that each step written with an equilibrium constant (i.e., K,KP ) is quasi-equilibrated, that each step with one direction arrow is irreversible, and the other steps are reversible. Derive the rate law for olefin hydrogenation in terms of the concentration of PPh3,H2, olefin and total Rh. Problem 1 (25 points).
