Consider the gas phase reaction
2 NO + H₂ → N₂O + H₂O
The experimental rate law is found to be R = [NO]²[H₂]
Which of the mechanisms shown below is consistent with the information about this reaction
given in this question?
Step 1: NO + H₂ → N + H₂O (slow)
Step2: N + NO → N₂O
(fast)
Step 1:
NO + NO
2 NO₂ + N
(slow)
(fast)
Step2: NO₂ + H₂
Step 3: N + NO
→ NO + H₂O
N₂O
(fast)
Step 1: NO + NO>>>
N₂O₂
Step2: N₂O₂ + H2 →→
N₂O + H₂O
