Question
A mechanism for the reaction of nitric oxide with hydrogen to form water and nitrogen gas is proposed below. What rate law is predicted by this mechanism?
2 NO(g) ⇌ N2O2(g) fast, unfavorable equilibrium
N2O2(g) + H2(g) → N2O(g) + H2O(g) slow, irreversible
N2O(g) + H2(g) → H2O(g) + N2(g) fast, irreversible
A.
Rate = k[NO]2
B.✓ Correct
Rate = k[NO]2[H2]
C.
Rate = k[NO]2[H2]2
D.
Rate = k[NO]2[H2]2 / [N2O][H2O]
