Question

NO2(g) + CO(g) → NO(g) + CO2(g)

The reaction between NO2(g) and CO(g) is represented above. The elementary steps of a proposed reaction mechanism are represented below.

Step 1: 2 NO2(g) → NO(g) + NO3(g) (slow)
Step 2: NO3(g) + CO(g) → NO2(g) + CO2(g) (fast)

Which of the following is the rate law for the overall reaction that is consistent with the proposed mechanism?

A.

Rate = k[NO2][CO]

B.

Rate = k[NO2]^2

✓ Correct
C.

Rate = k[NO3][CO]

D.

Rate = k[NO2][NO3][CO]
