ClO + O and Cl + O3. The net result of Cycle 1 is to con- vert one ozone molecule and one oxygen atom into two oxygen molecules. In each cycle chlorine acts
The cycle is made up of two basic reactions: Cl + O3 and ClO + O. The net result of Cycle 1 is to convert one ozone molecule and one oxygen atom into two oxygen

?eld observations of ClO and Cl 2O2 A value for Keq was de-termined from analysis of atmospheric measurements of ClO and Cl2O2 by von Hobe et al (2005) Avallone and Toohey (2001) also estimated a value for Keq based on atmospheric measurements of ClO and estimates of the concentration of Cl2O2 deduced assuming complete chlorine activation

ClO or Cl When starting with ClO the first reaction is ClO with O to form Cl Cl then reacts with (and thereby destroys) ozone and reforms ClO The cycle then begins again with another reaction of ClO with O Because Cl or ClO is reformed each time an ozone molecule is destroyed chlorine is con-sidered a catalyst for ozone destruc-tion
