The reaction below is first order in H₂ and second order in NO.What is the rate law for this reaction?
2 H₂(g) + 2 NO(g) → N₂(g) + 2 H₂O(g)

Question

The reaction below is first order in H₂ and second order in NO.What is the rate law for this reaction? 2 H₂(g)+ 2 NO(g)→ N₂(g)+ 2 H₂O(g)

Quizplus · Accepted Answer

The rate law is determined by the order of each reactant with respect to the reaction. Here, the power of H₂ is 1 and that of NO is 2. Therefore, the rate law will be k[H₂][NO]². Option B is the best choice as it matches the rate law.
