For this problem, we are being asked on what conditions would this reaction be first order in H2.
In this case, we have to revisit the steady-state approximation for the intermediates
Recall that the rate law only focuses on the reactant concentrations and has a general form of:
k = rate constant
A & B = reactants
x & y = reactant orders
The proposed mechanism for a given reaction is as follows:
Step One: 2 NO (g) N2O2 (g)
Step Two: H2(g) + N2O2(g) H2O(g) + N2O(g) Rate - determining Step
Step Three: N2O(g) + H2(g) N2(g) + H2O(g) Fast
Under what conditions would this reaction be first-order in H2? Please answer and justify your reasoning in 1-2 complete sentences on the line provided.
