question 91

Multiple Choice

What is the predicted rate law for the following mechanism for the reduction of nitrogen in NO by hydrogen?
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?

• A) Rate = k[H₂][NO]
• B) Rate = k[H₂]²[NO]
• C) Rate = k[H₂][NO]²
• D) Rate = k[H₂]²[NO]²
• E) More information is needed to answer this question.
