Rotating sector study of the gas phase photolysis of the carbon tetrachloride–cyclohexane system

Abstract

Abstract The rate constant for the combination of trichloromethyl radicals in the gas phase has been measured by applying the rotating sector technique to the gas phase carbon tetrachloride–cyclohexane photochemical system. A temperature‐independent rate constant, k 5 , of 3.9 ± 1.0 × 10 12 cc mole −1 sec −1 was found. Arrhenius parameters for the reaction were found to be given by the expression log k 4 = 11.79 – (10,700/2.3 RT ).
