The reaction of ozone with oxygen atoms in the presence of chlorine atoms can occur by a two step process shown below:
i. `O_(3)(g) + Cl^(*)(g) to O_(2)(g) + ClO^(*)`, `k_(1) = 5.2 xx 10^(9) "L mol"^(-1)s^(-1)`
(ii) `ClO^(*) (g) + O^(*)(g) to O_(2)(g) + Cl^(*), k_(II) = 2.6 xx 10^(10) L "mol"^(-1)s^(-1)`
The closest rate constant for the overall reaction
`O_(3)(g)+O^(.)(g)rarr2O_(2)(g)` is :`1.4 xx 10^(20) L mol^(-1) s^(-1)`, `3.1 xx 10^(10) L mol^(-1) s^(-1)`, `5.2 xx 10^(9) L mol^(-1) s^(-1)`, `2.6 xx 10^(10) L mol^(-1) s^(-1)`

Options

A. `1.4 xx 10^(20) L mol^(-1) s^(-1)`
B. `3.1 xx 10^(10) L mol^(-1) s^(-1)`
C. `5.2 xx 10^(9) L mol^(-1) s^(-1)`
D. `2.6 xx 10^(10) L mol^(-1) s^(-1)`
