2CF3O3CF32CF3O2CF3+O2 The following mechanism has been proposed to explain the observation that the reaction follows first order kinetics. (R1) (R2) (R3) Is this mechanism consistent with the stoichiometry of the overall reaction? Is this mechanism consistent with the first-order reaction kinetics that have been observed? (Regardless of your answer in a, use the mechanism as written to solve part b.)
