A proposed mechanism for the reduction of nitrogen as NO by hydrogen is:
Step 1: H₂(g) + 2 NO(g) $\rightarrow$ N₂O(g) + H₂O(g) (slow)
Step 2: N₂O(g) + H₂(g) $\rightarrow$ N₂(g) +H₂O(g) (fast) What is the rate law for step 2?

Question

A proposed mechanism for the reduction of nitrogen as NO by hydrogen is:
Step 1: H₂(g) + 2 NO(g)

\rightarrow

N₂O(g) + H₂O(g) (slow)
Step 2: N₂O(g) + H₂(g)

\rightarrow

N₂(g) +H₂O(g) (fast) What is the rate law for step 2?

Quizplus · Accepted Answer

The rate law for a reaction step is determined by the reactants and their stoichiometry in that step. Step 2 involves H₂ and N₂O as reactants, making the rate law k[H₂][N₂O].
