Final answer:
The reaction between nitrogen monoxide (NO) and hydrogen (H₂) has a rate law based on the slow step of the reaction, which is Rate = k[NO]^2[H₂], assuming the provided mechanism represents the elementary steps.
Step-by-step explanation:
The question involves a reaction where nitrogen monoxide, NO, reacts with hydrogen, H₂, to produce nitrogen, N₂, and water, H₂O. The rate law for this reaction given the mechanism:
- 2NO + H₂ → N₂ + H₂O₂ (slow)
- H₂O₂ + H₂ → 2H₂O (fast)
would be dependent on the concentrations of the reactants involved in the slow step. Assuming that the mechanism provided corresponds to the elementary steps of the reaction, the rate law would be Rate = k[NO]^2[H₂], where k is the rate constant for the slow step.
