B) One chlorine atom can catalyze the destruction of hundreds to thousands of O₃ molecules.
C) Chlorine atoms react with O₃ to make ClO,another reactive species.
D) Chlorine atoms are regenerated when chlorine monoxide reacts with O₂.
E) The speed with which O₃ decomposes is greatly enhanced in the presence of Cl atoms,which provide a lower-energy reaction mechanism.
