Notes:
The gamma-radiation-induced free-radical chain reactions in liquid CCl4—C2Cl4—c—C6H12 mixtures were studied in the temperature range of 363-448°K. The main products in this system are chloroform, hexachloropropene and chlorocyclohexane. These products are formed via reactions (1)-(5): with G values (molec/100 eV) of the order of magnitude of 102 and 103 at the lowest and highest temperatures, respectively. Values of k2/k1 were determined from the product distribution. In turn, these values gave the following Arrhenius expression for k2/k1 (θ = 2.303RT, in kcal/mol): \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm log }\,k_2 /k_1 = ( - 1.21 + 0.10) + (1.59 \pm 0.27)/\theta $$\end{document} From this result and the previously determined Arrhenius parameters of reaction (1), k2 is found to be given by \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm log }\,k_2 (1/{\rm mol} \cdot {\rm sec) = 7}{\rm .58 - 9}{\rm .49/}\theta $$\end{document}.
