The mechanism of the reaction,

$2NO(g) + 2{H_2}(g) \to {N_2}(g) + 2{H_2}O(g)$ is :

Step $1$ : $2NO(g) + {H_2}(g)\xrightarrow{{slow}}{N_2} + {H_2}{O_2}$

Step : $2$ ${H_2}{O_2} + {H_2}\xrightarrow{{fast}}2{H_2}O$

Then the correct statement is

  • A

    Rate $= k{\left[ {NO} \right]^2}\,{\left[ {{H_2}} \right]^2}$ 

  • B

    Rate $= k \left[ {{H_2}{O_2}} \right]\,\left[ {{H_2}} \right]$

  • C

    On doubling the concentration of $H_2$ , keeping the concentration, of $'NO'$ constant, the rate will become double

  • D

    If the initial concentration of $H_2$  and  $NO$ is $C_0$ and after time $'t'$ the concentration of  $N_2$ is $x$ , then Rate $= K{\left( {{C_0} - 2x} \right)^2}$
