The decomposition of hydrogen peroxide is catalyzed by, Ask an Expert

Academics

The decomposition of hydrogen peroxide is catalyzed by iodideion. The catalyzed reaction is thought to proceed by a two-stepmechanism:

1.H₂O_2(aq) + I^-_(aq) → H₂O_(l)+IO^-_(aq)(slow)

2.IO^-_(aq) +H₂O_2(aq)→H₂O_(l)+O_2(g)+I^-_(aq) (fast)

a. Assuming that the first step of the mechanism is ratedetermining, predict the rate expression for the overallprocess.

b. Write the chemical equation for the overall process.

c. Identify the intermediate, if any, in the mechanism.d. What distinguishes an intermediate from a catalyst in the chemical reaction
