Reaction mechanism answers
Answers to Reaction mechanism questions 1. (a) If the second step is the slowest step the overall rate will equal the rate for that step. The rate for the second step is proportional to [H2(g)] and [N2O2(g)], i.e.rate ∝ [H2(g)] x [N2O2(g)] or rate = k[H2(g)][N2O2(g)] where k is the rate constant.However N2O2(g) is an intermediate and its formation depends on the first step, i.e. [NO(g)]2.
