Consider the following proposed reaction mechanism: Step 1: F2 + 2 NO2 → NO2F + F + NO2 Step 2: F + NO2 → NO2F The first step is the slow (rate-determining) step. Answer the following questions: Question 31: The intermediates in the overall equation are: F2 NO₂F NO2 F Check Question 32: If this mechanism is correct, the rate law of the overall reaction would be rate = k₁[F2][NO2] Cannot be determined rate = k₁[[NO₂F]² rate = k₁[F2]²[NO2]² rate = = K₁[F2][NO2]² Check
