3.22 M. Santos Alfonso and H. J. Schumacher [Int. J. Kinet., 16,
103 (1984)] studied the kinetics of the gas-phase reaction
between hexafluoropropene and trifluormethyhypofluorite at
75°C:
C;F, + CF,OF → C,F,OCF,
They have reported that the reaction is (2)-order in CF,OF
and (2)-order in C,F,.
Consider the case where this reaction is carried out
isothermally at a constant pressure of 800 torr in a variable
volume batch reactor. At the temperature of interest, the
value of the rate constant is 1.30 M-/s. The initial mixture
consists of equal moles of C,F, and CF,OF. Determine the
time necessary for the concentration of C,F, to decrease to
