The mechanism of the reaction, $2 N O (g) + 2 H_{2} (g) \to N_{2} (g) + 2 H_{2} O (g),$ is
Step 1: $2 N O (g) + H_{2} (g) \overset{s l o w}{\to} N_{2} + H_{2} O_{2}$
Step 2: $H_{2} O_{2} + H_{2} \overset{f a s t}{\to} 2 H_{2} O$
Select the correct statement

Answer:

Solution:

As slowest step is the rate determining.
Rate $= k [N O]^{2} [H_{2}]$
So on doubling the concentration of $H_{2}$ without changing the concentration of NO, the rate will become double.
