For a reaction, 2NO + 2H₂ → N₂ + 2H₂O, the possible mechanism is
2NO N₂O₂
N₂O₂ + H₂ N₂O + H₂O
N₂O + H₂O N₂ + H₂O
What is the rate law and order of the reaction?

1. Rate = [N₂O₂], order = 1
2. Rate = [N₂O₂][H₂], order = 2
3. Rate = [N₂O₂]², order = 2
4. Rate = [N₂O₂]² [H₂], order = 3

Answer

(D) Rate = [N 2 O 2 ] 2 [H 2 ], order = 3
