The destruction of ozone layer is chemical change. The chemical equation for destruction of ozone can be written as:
Cl + O₃ → ClO + O₂ – The chlorine atom changes an ozone molecule to ordinary oxygen.
As during the reaction, ozone molecules destroy and oxygen molecules form. So new chemical substances are formed by consuming the starting material hence it is a chemical change.
