4. (22 pts) Consider the following exothermic reaction: H2O2 +2t + 2H → 12 + 2H20 Consider the following mechanism for this reaction H,02 + r-* Hol + OH Hol + r- 12 + он. 20H 2H2 H20 slow fast fast a) What species are intermediates in the above mechanism? Any catalysts? b) Sketch an energy versus reaction progress plot for the three step mechanism and clearly label the rate determining step in your diagram. c) What rate law would be expected if this mechanism is correct? That is, will it be zero- order, first-order or second-order with respect to H202? Zero-order, first-order or second- order with respect to 1? Explain briefly. d) What rate law would be expected if the second step in this reaction mechanism is the slow step?
