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 ^ (g) → O₂(g) + ClO ^ (g)......(i) k i = 5.2 × 10⁹ L mol^−1 s^−1 ClO ^ (g) + O ^ (g) → O₂(g) + Cl ^ (g)...... (ii) k i i = 2.6 × 10¹⁰ L mol^−1 s^−1 The closest rate constant for the overall reaction O₃(g) + O ^ (g) → 2 O₂(g) is:

(D) 1.4 × 10²⁰ L mol^−1 s^−1

(A) 5.2 × 10⁹ L mol^−1 s^−1
