Few researchers studied the kinetics of the gas-phase reaction between S4 and CF3OF. This reaction obeys the rate expression r=k(SF4)(CF3OF) The following mechanism has been proposed to explain the kinetics of this reaction: SF4+CF3OFk1SF5+CF3O.SF5+CF3OFk2SF6+CF3O.CF3O+CF3OFk3CF3OOCF3+F.F+SF4k4SF5.CF3O+SF5k5CF3OSF5 (a) Is this mechanism consistent with the observation that the products consist primarily of equimolal quantities of SF6 and CF3OOCF3, together with very small quantities of CF3OSF5? (b) Determine the rate expression corresponding to these mechanistic equations. (c) Is this rate expression consistent with the experimental results
