Solution: In 1995, Mario Molina, Paul Crutzen, and F. Sherwood Rowland shared the Nobel Prize in chemistry for their work on atmospheric chemistry. One reaction sequence they proposed for the role of chlorine in the decomposition of stratospheric ozone (we’ll see another sequence in Chapter 16) is

(1) Cl(g) + O3(g) ⟶ ClO(g) + O2(g) 
(2) ClO(g) + ClO(g) ⟶ Cl2O2(g) 
(3) Cl2O2(g) light ⟶ 2 Cl(g) + O2(g) 

Over the tropics, O atoms are more common in the stratosphere:

(4) ClO(g) + O(g) ⟶ Cl(g) + O2(g) 

Write an overall equation combining reactions 1–3.
