Q .     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^{\bu ll et}(g) \rightarrow O_2(g) + ClO^{\bu ll et} (g)` ....(i)

` k_i= 5.2 \times 10^9 L\, mol^{-1} s^{-1}`

`ClO^{\bu ll et} (g) + O^{\bu ll et} (g)\rightarrow O_2(g) + Cl^{\bu ll et} (g) ` ...(ii)

` k_{ii} = 2.6 \times 10^{10} L\, mol^{-1} s^{-1}`

The closest rate constant for the overall reaction `O_3(g) + O^{\bu ll et} (g) \rightarrow 2 O_2(g)` is :
