A posible mechanism for the reaction :
`2NO + 2H_(2) to N _(2) + 2H_(2) O` is :
(i) `2NO + overset(k _(1))hArr N _(2) O _(2)`
` (ii) N _(2) O _(2) + H _(2) overset(k _(2))to N _(2) O + H _(2) O`
(iii)` N _(2)O + H _(2) overset(k _(3)) to N _(2) + H _(2)O`
If the second step is the rate determining step then rate law may be written as : ?

A

Rate= `k [N _(2)O_(2)] [H_(2)]`

B

Rate `=k [NO] [H_(2)]`

C

Rate `=k [NO]^(2)[H_(2)]`

D

Rate `=k [NO] [H_(2)] ^(2).`
