    The ultraviolet light is simply a source of energy, and is being used to break bonds. In fact, the energies in UV are exactly right to break the bonds in chlorine molecules to produce chlorine atoms.

    The productive collision happens if a chlorine radical hits a methane molecule. A chlorine radical : Cl2 -> 2 CL* .

    So only Cl can bound with CH4 not Cl2. and the UV just break the chlorine.
