Question

Consider this reaction.
2H2(g) + 2NO(g) → N2(g) + 2H2O(g)
The rate law for this reaction is rate = k [H2] [NO]^2. Under what conditions could these steps represent the mechanism?
Step 1. 2NO = N2O2
Step 2. N2O2 + H2 → N2O + H2O
Step 3. N2O + H2 → N2 + H2O

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.

✓ Correct
D.

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