a two step reaction mechanism is proposed for a gas phase reaction, as represented above. which of the follwoing correctly identifies both the chemical equation for step 1 and the rate law for the overall reaction? 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) → 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]".
