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

Cl atoms are used in first reaction, but regenerated in second, so overall they are not consumed – Cl atoms act as a catalyst (c) Is ClO a catalyst or a reaction intermediate? ClO is a reaction intermediate (d) What distinguishes a catalyst from an intermediate? A catalyst is not consumed in the overall process, whereas an
