    You could add O3 -> O2 + O. (O. appearing in step two of propagation).

    I prefer ClO. + O3 -> Cl. + 2O2 in step 2.

    why the author doesnt include the reaction equation O3 -> O2 + O. in the notes? this is making me confused.....

    can you explain how is the equation ClO. + O3 -> Cl. + 2O2 in step 2. different form the propagation steps in the books?

    I may be wrong (although Wikipedia agrees with my version of the equation), but it makes kinetic sense.

    There is lots of O2 and some O3 in the high atmosphere. A small number of these are zapped by u.v. forming some O.

    CFCs are zapped by u.v. forming a few Cl.

    What is Cl. going to bump into? Most likely O2 or O3, forming a ClO. But what will that bump into? Most likely O2 or O3, how often will it bump into an O.?
