Q 2124756651.     Consider the reaction: ` 2H_2 (g) +2NO (g) ->N_2( g) + 2H_2O (g)`
The rate law for this reaction is
Rate `= K[H_2] [NO]^2`
Under what conditions could these steps represent the mechanism?

Step :1 `2NO ⇋ N_2 O_2`
Step : 2 `N_2 O_2 + H_2 -> N_2 O + H_2 O`
Step : 3 `N_2 O + H_2 -> N_2 + H_2 O`
A

These steps cannot be the mechanism under any circumstances

B

These steps could be the mechanism if step 1 is the slow step

C

These steps could be the mechanism if step 2 is the slow step

D

These steps could be the mechanism if step 3 is the slow step
