10. Nitrogen monoxide, NO, reacts with hydrogen, H 2, according to the following equation:
2NO(g) + 2H₂(g) → N₂(g) + 2H₂O(g)
If the mechanism for this reaction were,
2NO(g) + H₂(g) → N₂(g) + H₂O₂(g) ; slow
H2O₂(g) + H₂(g) → 2H₂O(g) ; fast
Which of the following rate laws would we expect to obtain experimentally?

Rate = k[H₂O₂][H₂]

Rate = k[NO]₂[H₂]

Rate = k[NO]₂[H₂]₂

Rate = k[NO][H₂]
