Question
Nitric oxide is formed at high temperature in the presence of oxygen and nitrogen. A proposed mechanism for its formation is shown:
O2(g) ⇌ 2 O(g) fast, unfavorable
N2(g) + O(g) NO(g) + N(g) slow
N(g) + O(g) NO(g) very fast
What rate law is predicted by this mechanism?
A.
Rate = k[O2]
B.
Rate = k[N2][O2]
C.✓ Correct
Rate = k[N2][O2]1/2
D.
Rate = k[N2][O2]2
