For the reaction

2{H_2}(g)\, + \,2NO(g)\, \to \,{N_2}\,(g)\, + \,2{H_2}O(g)

The observed rate expression is, rate

= \,{k_f}\,{[NO]^2}[{H_2}].

The rate expression for the reverse reaction is

View answer and explanation

Correct option: A

{k_b}[{N_2}]{[{H_2}O]^2}\,/\,[{H_2}]

Option A (

{k_b}[{N_2}]{[{H_2}O]^2}\,/\,[{H_2}]

) is correct because it is derived from the equilibrium constant expression using the given forward rate law.
