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.✓ Correct
Rate = k[NO2]^2
C.
Rate = k[NO3][CO]
D.
Rate = k[NO2][NO3][CO]
