Description
Summary:The kinetics of the reaction of CHCl2 radical with O(3P) atoms has been studied in a heatable tubular reactor coupled to a photoionization mass spectrometer. The time-resolved decay of CHCl2 was monitored as a function of O atom concentration (in a large excess of O atoms). The rate constants show a weak dependence on temperature over the 302−900 K range and can be represented by an Arrhenius expression k(T) = k 3 = (9.00 ± 0.92) × 10-11exp(57.4 ± 19.1 K/T) cm3 molecule-1 s-1. HCl was detected as a product of the CHCl2 + O(3P) reaction.
