Abstract

Rate constants are calculated for CH~3~ (+ Ar) ⇄ CH~2~ + H (+ Ar) at the limiting low‐pressure, the limiting high‐pressure, as well as the intermediate fall‐off ranges. The results show that published experimental rate constants for methyl dissociation correspond to the fall‐off region close to the low‐pressure limit. At the low‐pressure limit the activation energy is less than the bond dissociation energy, in agreement with experimental results. Forward and backward rate coefficients at the high‐pressure limit are compared with other theoretical calculations. More theoretical and experimental work is necessary to understand the reverse reaction and its competing reactions, as well as the decomposition channel leading to CH + H~2~. © 1994 John Wiley & Sons, Inc.

## Abstract 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: at 900 K, where the __A__ factor was assumed to be the same as for 2,2′‐azoisobutane. The h
