| Résumé : | The photochemical reaction between gaseous Cl2, C2Cl4 and C2Cl5H has been further investigated. From the general reaction scheme previously proposed equations have been calculated and tested experimentally for the rate of the reaction Cl2 + C2Cl5H → C2Cl6 + HCl yielding 2 relations between rate constants; the total rate of disappearance of Cl2 in mixtures of C2Cl4 + C2Cl5 H; the competition addition‐substitution; the competition substitution‐dehydrohalogenation; the competition dehydrohalogenation‐addition; With the previously studied relations for; the rate of addition at low temperatures; the rate of addition at high temperatures; the rate of dehydrohalogenation; relations are now available between 6 rate constants. But since these relationships are not independent, complex rate constants can be determined only e. g. for the four independent combinations. (Formula Presented.) Since 9 rate equations are available each of these complexe rate constants has been determined by at least 2 independent methods yielding thus a very reliable proof of the mechanism.
