a. chlorofluorocarbons
Explanation:
The chemical reaction describes the combination of chlorofluorocarbons with ozone.
Reaction 1: ClO + BrO ⇒ Cl + Br + O₂
Reaction 2: Cl + O₃ ⇒ ClO + O₂
Reaction 3: Br + O₃ ⇒ BrO + O₂
O₃ is the ozone molecule, the Cl, and Br are the chlorofluorocarbons.
- In this reaction, ozone is converted into oxygen gas. This reaction takes place in the stratosphere.
- This leads to the penetration and creation of a hole in the atmosphere which allows for ultraviolet rays to reach the earth surface.
- The chlorofluorocarbons are produced on the earth surface in component gases used for making refrigerants, car sprays, air conditioners etc.
- When the reach the ozone layer, they react with it and produce oxygen gas.
