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

C. `k'N_2O[H_2]`
D. `k'N_2O_2`

Answer

A
