For the reaction,
`2H_(2)(g)+2NO(g) rarr N_(20(g) +2H_(2)O(g)`
Rate `=k[H_(2)][NO]^(2)`.
This mechanism has been proposed:
Step 1: `H_(2)+NO rarr H_(2)O+N`
Step2 : `N=NO rarr N_(2)+O`
Step 3 : `O+H_(2) rarr H_(2)O`
Which statement about this rate law and mechanism is correct?

A

The mechanism is consistent with the rate law if step 1 is the rate determineing step.

B

This mechanism is consistent with the rate law if step 2 is the rate detemining step.

C

The mechanism is consistent with the rate law if step 3 is the rate determining step.

D

This mechanism can not be consistent with the rate law, regardless of which step is rate-determining.
