Notes:
The unimolecular homogeneous decomposition of hexafluoroazomethane was studied in a VLPP apparatus in the temperature range 720-1050 K and is consistent with the following Arrhenius parameters: \documentclass{article}\pagestyle{empty}\begin{document}$$ \log k(\sec ^{ - 1}) = 16.2 - 55.2/\theta $$\end{document} at 900 K, where the A factor was assumed to be the same as for 2,2′-azoisobutane. The homogeneous rate of recombination of ·CF3 radicals at temperatures around 1000 K was also studied under VLPP conditions and was found to be in the fall-off region, corresponding to k/k∞ = 8.5 × 10-3 when a rotational transition-state model was used. This model predicts an essentially constant value of kr∞ of 109.7 over the temperature range 300-1000 K.
