Kinetics study of the Cl/2P/ + Cl2O yields Cl2 + ClO reaction at 298 K

The kinetics of the Cl + Cl2O reaction, a possible source of ClO(2 Pi) radicals for atmospheric photochemical studies, are investigated at 298 K. The discharge flow/mass spectrometry and discharge flow/resonance fluorescence techniques were used to monitor the decay of C12O in the presence of excess concentrations of atomic chlorine and chlorine monoxide, respectively. The pseudo-first order rate constants obtained from both experiments are found to be in excellent agreement, averaging 9.8 + or - 0.8 x 10 to the -11th cu cm/molecule per sec. Results are consistent with the lower limit obtained by Edgecombe et al. (1957) but differ by a factor of 150 from those of Basco and Dogra (1971). The present value is also noted to be consistent with a lower value for the rate constant of the reaction of oxygen atoms with Cl2O.

Rate constants for the reactions of OH with ClO, Cl2, and Cl2O at 298K

Recent concern about the depletion of stratospheric ozone by chlorine species from the decomposition of chlorofluoromethanes has emphasized the need for laboratory studies of the first reaction steps involved, especially those which control the concentration of the OH and ClO radicals in the stratosphere. Rate constants for the reactions of OH with ClO, Cl2, and Cl2O at 298 K have been determined in a discharge flow system using resonance fluoresence detection. The results are (9.1 + or - 1.3) x 10 to the -12th, (5.5 + or - 0.3) x 10 to the -14th, and (6.5 + or - 0.5) x 10 to the -12th (all in units of cu cm/sec), respectively.

Pressure Dependence and Metastable State Formation in the Photolysis of Dichlorine Monoxide (Cl2O)

Physics%K photolysis, dichlorine monoxide, pressure%U http://techreports.jpl.nasa.gov/1995/95-0924.pdfThe photodissociation of dichlorine monoxide (Cl2O) was studied using broadband flash photolysis to investigate the influence of variations in the photolysis wavelength domain, bath gas pressure, and bath gas identity on the yield and temporal dependence of the ClO product. ClO yields were independent of bath gas pressure when the photolysis spectral band extended to 200 nm (quartz cutoff) but for photolysis restricted to wavelengths longer than about 250 nm, ClO yields decreased with increasing bath gas pressure and there was a pressure-dependent delay in the formation of ClO.!.
