Question

A possible mechanism for the reaction is: HOOH + H+ ? HOOH2+ (rapid equilibrium, small K) I? + HOOH2+ ? IOH + H2O (rate determining step, k2) IOH + H+ + I? ? I2 + H2O (rapid equilibrium, large K) where K is an equilibrium constant. Sketch a potential energy diagram for the reaction using the mechanism in Q4 as a guide. On the sketch, indicate the presence of reactants, products and intermediates.

Step 1

In the first step, HOOH and H+ are in equilibrium with HOOHz. This is a rapid equilibrium with a small K, so the energy barrier is low and the energy of HOOHz is slightly higher than that of HOOH and H+. Show more…

A possible mechanism for the reaction is: HOOH + H+ ⇌ HOOH2+ (rapid equilibrium, small K) I− + HOOH2+ → IOH + H2O (rate determining step, k2) IOH + H+ + I− ⇌ I2 + H2O (rapid equilibrium, large K) where K is an equilibrium constant.
