Step 1: (slow)
Step 2: NO3(g) + CO(g) + NO2(g) + CO2(g) (fast)
Overall: NO2(g) + CO(g) + NO(g) + CO2(g)
A two-step reaction mechanism is proposed for a gas-phase reaction, as represented above. Which of the following correctly identifies both the chemical equation for step 1 and the rate law for the overall reaction?
A) The chemical equation for step 1 is 2 NO2(g) β NO(g) + NO3(g), and the rate law is rate = (NO,].
B) The chemical equation for step 1 is NO2(g) + CO(g) + NO(g) + CO2(g), and the rate law is rate = [NO2][CO).
C) The chemical equation for step 1 is NO3(g) + 2 CO(g) + NO(g) + 2 CO2(g), and the rate law is rate = [NO2][CO).
D) The chemical equation for step 1 is NO3(g) + NO2(g) + 2 CO(g) + NO(g) + NO2(g) + 2 CO2(g), and the rate law is rate = [NO3][NO2][CO]".
