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 the mechanism under any circumstances.
B. Theses steps could be the mechanism if step 2 is the slowest step
C. These steps could be the mechanism if step 3 is the slowest step
D. These step could be the mechanism if step 3 is the slowest step

Answer

C
