question 187

Multiple Choice

A proposed mechanism for the reaction 2 NO(g) + 2 H₂(g) $\to$ N₂(g) + 2 H₂O(g) is Step 1: 2 NO(g) $\to$ N₂O₂(g)
(very fast,reversible)
Step 2: N₂O₂(g) + H₂(g) $\to$ N₂O(g) + H₂O(g) (slow)
Step 3: N₂O(g) + H₂(g) $\to$ N₂(g) + H₂O(g) (fast)
What is the rate law for the overall reaction?

• A)k[NO]/[N₂O₂]
• B)k[N₂O][H₂]
• C)[NO]²
• D)k[NO]^1/2[H₂]
• E)k[NO]²[H₂]
