Question
For the reaction; 2H2(g) + 2NO(g) → N2(g) + 2H2O(g), rate = k[H2][NO]2. This mechanism has been proposed:
step 1: H2 + NO → H2O + N
step 2: N + NO → N2 + O
step 3: O + H2 → H2O
Which statement about this rate law and mechanism is correct?
A.
This mechanism is consistent with the rate law IF step 1 is the rate determining step.
B.✓ Correct
This mechanism is consistent with the rate law IF step 2 is the rate determining step.
C.
This 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.
