Abstract Rate constants determined for the thermal dimerization of chlorotrifluoroethene to dichlorohexafluorocyclobutane at 404–672 K have been correlated with previously published results. For the temperature range of 404–800 K,\documentclass{article}\pagestyle{empty}\begin{document}$$ k{ = 1}{.08} \times { 10}^{{ - 9}} { T }^{{4}{.02}} { exp ( - 86,700/RT) m}^{3} {/mol} \cdot \sec $$\end{document} The dependence of the preexponential factor on temperature corresponds to a value of 17 J/K·mol for the difference in heat capacity (Δ C p ± ) between the activation complex and the reactant.
