Kinetics of the Reaction of C₂Cl₃ with Cl₂

The reaction C₂Cl₃ + Cl₂ → C₂Cl₄ + Cl has been studied using the laser photolysis/photoionization mass spectrometry technique. Rate constants were determined in time-resolved experiments as a function of temperature (299−668 K). Rate constants of the above reaction are independent of the bath gas density within the experimental range, [He] = (3−12) × 10¹⁶ atom cm^-3. Within the above experimental range of temperatures, the rate constants of the above reaction can be described by the modified Arrhenius expression k₁ = 3.79 × 10^-15 T^0.87 exp(−55 K/T) cm³ molecule^-1 s^-1.
