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

$O_{3} (g) + {Cl}^{•} \to O_{2} (g) + {ClO}^{•} (g)$ ...(i)

$k_{i} = 5.2 \times 10^{9} L m o l^{- 1} s^{- 1}$

${ClO}^{•} (g) + O^{•} (g) \to O_{2} (g) + {Cl}^{•} (g)$ ...(ii)

$k_{i i} = 2.6 \times 10^{10} L m o l^{- 1} s^{- 1}$

The closest rate constant for the overall reaction

$O_{3} (g) + O^{•} (g) \to 2 O_{2} (g)$ is:
