M. dos Santos Afonso and H. J. Schumacher pInt. J. Chem. Kinet. 16, 103-115 (1984)] reported that the rate law for the gas-phase reaction between CF3OF and C3F6 is r = k,(CF30F)(C3F6) + k2(CF30F)/2(C3F6)/2 At 75 C, the values of ki and k2 are 8.67x102 and 1.16 M/s, respectively. For practical purposes, the stoichiometry of this reaction is C3F6 + CF3OF > C3F7OCF3 Consider the design of a small tubular reactor capable of processing 10 L/min of a 4:1 v/v mixture of CF3OF and C3F6 to achieve 95% conversion of the limiting reagent. The reactor is to operate isothermally at 75 C at a pressure of 1 bar. The internal diameter of the tube is 5 cm. What length of tube will be required? (Problem 8.9 in Hill)
