Notes:
The kinetics of the thermal reaction between SF4, and CF3OF has been studied between 142°C and 185°C. The reaction was found to be homogeneous and the only products formed are equimolecular amounts of SF6 and CF3O2CF3 and smaller amounts of CF3OSF5. The reaction mechanism was not affected by the total pressure, the oxygen pressure, or by the buildup of products. The experimental data can be explained by the following mechanism: The rate constants can be expressed as \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{lr} k_1 = (4.58 \pm 0.30) \times 10^7 \,{\rm exp( - 18900} \pm {\rm 1000}\,{\rm cal/}RT)M^{ - 1} \,{\rm s}^{{\rm - 1}} \\ k_2 = (3.88 \pm 0.30) \times 10^9 \,{\rm exp( - 9800} \pm {\rm 1000}\,{\rm cal/}RT)M^{ - 1} \,{\rm s}^{{\rm - 1}} \end{array} $$\end{document}
