What is the word equation for this reaction?

Cl + O3 → ClO + O2

The bimolecular rate constant for the reaction Cl + O3 → ClO + O2 is measured over the temperature range 210 to 360 K in a discharge flow system using Cl atom resonance fluorescence at 134.72 nm to monitor the decay of Cl under pseudo first order conditions. Results, expressed in the form k1 = (2.35 ± 0.5) * 10-11 exp[ - (171 ± 30) / T], are compared with other recent studies of this reaction. Stratospheric implications are discussed briefly including the possibility of a concurrent three-body mechanism with O2 forming ClO3.
