Consider the reaction :
`2H_(2)(g)+2NO(g)rarrN_(2)(g)+2H_(2)(g)`
The rate law for this reaction is :
Rate = `k[H_(2)][NO]^(2)`
Under what conditions could these steps represent mechanism?
`{:("Step 1:",2NO(g)hArrN_(2)O_(2)(g)),("Step 2:",N_(2)O_(2)+H_(2)rarrN_(2)O+H_(2)O),("Step 3:",N_(2)O+H_(2)rarrH_(2)O+N_(2)):}`

Options

A. These steps cannot be he mechanism under any circumstaces
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

Answer

C
