Q

identify the radical produced from CFC’s that are responsible for the depletion of the ozone in the atmosphere

explain with equations, why a single radical can cause the decomposition of many molecules of ozone

A

chlorine

. .
Cl + O3 —> ClO + O2

.                    . ClO + O3 ---> Cl + 2O2

Cl is regenerated and causes a chain reaction in the decomposition of ozone
