For the reaction 2H(2)(g)+2NO(g) rarr ...

For the reaction
`2H_(2)(g)+2NO(g) rarr N_(2)(g)+2H_(2)O(g)`
the observed rate expression is, rate `=k_(f)[NO]^(2)[H_(2)].` The rate experssion for the reverse reaction is :

A

(a) `k_(b)[N_(2)][H_(2)O]^(2)//[H2]`

B

(b) `k_(b)[N_(2)][H_(2)O]^(2)`/[ NO]

C

(c) `k_(b)[N_(2)O]^(2)//[H_(2)]`

D

(d) `k_(b)[N_(2)][H_(2)O]`
