Prediction of the Rate Coefficient for the F+SOF₃ Recombination Reaction

Abstract

The pressure dependence of the rate coefficient for the recombination reaction SOF₃+F → SOF₄ has been calculated by utilizing an RRKM canonical variational approach with a hindered-rotor Gorin potential surface. With no adjustable parameters, the high-pressure recombination rate coefficient is predicted to be c. 1×10^-10cm³s^-1. It was further established that this rate coefficient is close to its high-pressure limit above c. 100 Pa. These results support the conclusions of an experimental study in which this rate coefficient was measured relative to that of the association reaction between SOF₃ and O.
