✦ Synopsis
The bimolecular rate constant for the reaction Cl + 03 -Cl0 + O2 is measured over the temperature range 210 to 360 K in it dischare flow system using Cl nfom rcsonzncc fluorescence at 134-72 nm to monitor the decay of Cl under pseudo fist order conditions. Results, expressed in the form k, = (2.35 i 0.5) X 1O-11 esp[-(171 + 30)/T], arc compared with other recent studies of this reaction. Stratospheric implications are discussed briefly including the possl%ilitY of a concurrent thee-body mechanism with 02 forming ClOs.
