Mechanisms with equilibrium steps. A. Overall reaction: H 2 + Br 2 2 HBr Proposed Mechanism: (i) Br 2 2 Br fast equilibrium (ii) Br + H 2 HBr + H slow (iii) H + Br 2 HBr + Br fast Derive the rate law consistent with this mechanism. B. Overall reaction: Cl 2 + CO Cl 2 CO Proposed Mechanism: ("M" is an inert molecule that acts as a catalyst) (i) Cl 2 + M 2 Cl + M fast equilibrium, k 1 (ii) Cl + CO + M ClCO
