For the reaction mechanism of the reaction
`{:(2NO(g)+2H_(2)(g))toN_(2)(g)+2H_(2)O(g):}`
`{:("Step I":2NOoverset(k_(1))hArrN_(2)O_(2) K_(eq)"(fast)")
("Step II:"N_(2)O_(2)+H_(2)overset(k_(2))rarrN_(2)O+H_(2)O"(slow)")
("Step III:"N_(2)O+H_(2)overset(k_(3))rarrrN_(2)+H_(2)O"(fast)"):}`
Expression of rate of reaction is
(Take `K_(eq) xx k_(2) = k')`

Options

A. `k'[NO]^(2)[H_(2)]`
B. `k'N_(2)O_(2)[H_(2)]`
C. `k'N_(2)O[H_(2)]`
D. `k'N_(2)O_(2)`

Answer

A
