The reaction of ozone with oxygen atoms in the presence of chlorine atoms can occur by a two step process shown below :

O₃(g) + Cl$${^ \bullet }$$ (g) $$ \to $$ O₂(g) + ClO$${^ \bullet }$$ (g) . . . . . .(i)

k_i = 5.2 × 10⁹ L mol⁻¹ s⁻¹

ClO$${^ \bullet }$$(g) + O$${^ \bullet }$$(g) $$ \to $$ O₂(g) + Cl$${^ \bullet }$$ (g) . . . . . . (ii)

k_ii = 2.6 × 10¹⁰ L mol⁻¹ s⁻¹

The closest rate constant for the overall reaction O₃(g) + O$${^ \bullet }$$ (g) $$ \to $$ 2 O₂(g) is :
