Chlorofluorocarbons photodissociate to produce chlorine atoms, Cl; which have been implicated in decreasing the concentration of ozone, O3, in the stratosphere. The decomposition of the ozone follows a reactiong sequence of

O3+Cl: --> ClO +02
ClO + O ---> Cl+ O2

What role ( factor affecting reaction rates) do chlorine atoms have in increasing the depletion rate of ozone?

OPTIONS: NATURE OF THE REACTANTS
TEMPERATURE OF THE CHEMICAL SYSTEM
PRESENCE OF A CATALYST
CONCENTRATION OF THE REACTANTS
OR
SURFACE AREA OF THE REACTION???
