Abstract: | ![]() The kinetics of gamma-radiation induced free radicals reactions in carbon tetrachloride solutions of cyclohexane, cyclooctane and cyclododecane were studied in the range of 27–190°C. The activation energies found were in the order c? C6H12 > c? C12H24 > c? C8H16, which was explained as due to their ring strain which has the same order. The following log k1 was obtained using the known Arrhenius parameters for CCl3 radical recombination: ![equation image equation image](/cms/asset/7b8be27a-6c87-407e-b65e-9a49d874c610/nueq001.gif) |
