Problem
Kinetic analysis of the reaction R → V in the presence of a catalyst Cat yields the following information:
• The reaction energy profile has four distinct transition states.
• The first activation barrier is the largest, making the first step rate-determining.
• Two intermediates, I₁ and I₂, accumulate to detectable concentrations; no others are observed.
Four mechanisms are proposed:
(a) Mechanism I
(b) Mechanism II
(c) Mechanism IV
(d) Mechanism III
