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

Question

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

\rightarrow

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

\rightarrow

N₂(g) + H₂O(g)
What is the molecularity of step 1?

Quizplus · Accepted Answer

The molecularity of a reaction step is determined by the number of reactant molecules involved in that step. In step 1, there are three reactant molecules: 1 H2 and 2 NO, making it termolecular.
