Reactions of chromium atoms with chloromethanes

The rate constants of the gas-phase reactions of the chromium atom with CC14, CHC13, and CH2Cl2 were measured behind shock waves at 800–1400 K. The results are presented in the Arrhenius form (the activation energy is given in kJ/mol):k CCl 4 = 1014.32±0.36exp[-(2.0±7.5)/RT],k CHCl 3 = 1014.72±0.21exp[-(18.5.±4.0)/RT, andk CH 2 Cl 2> = 1014.33±0.16exp[-(24.1±3.1)/RT]cm3mol-1s-1.
