The reaction 2 NO(g) + H2(g) --> N2O(g) + H2O(g) proceeds through the following mechanism: 2 NO(g) --> N2O2(g) N2O2(g) + H2(g) --> H2O(g) + N2(g) (b) What would the rate law be if the first step of this mechanism were rate-determining? Rate = k [NO] [H2]Rate = k [NO]2 [H2] Rate = k [NO] [H2]2Rate = k [NO]1/2 [H2] Rate = k [NO] [H2]1/2 Rate = k [NO]2 Rate = k [NO]2 [H2]1/2 Rate = k [NO]

The nitrogen-monoxide-catalyzed decomposition of dinitrogen monoxide is thought to proceed by a two-step mechanism: NO(g) + N2O(g) --> N2(g) + NO2(g) (slow) 2 NO2(g) --> 2 NO(g) + O2(g) (a) If the first step of this mechanism is rate-determining (slow), choose the correct rate law for the overall process. Rate = k [N2O]2 Rate = k [NO] [NO2] Rate = k [N2O]2 [N2O] Rate = k [NO2] [N2O] Rate = k [N2O] [N2O] Rate = k [NO] [N2O] (b) Choose...
