Correct option is A
Ozone (O₃) is created when diatomic oxygen (O₂) is exposed to solar ultraviolet (UV) radiation.
Ozone (O₃) is formed in the
stratosphere through the action of
ultraviolet (UV) radiation on
oxygen molecules (O₂).
The process occurs as follows:
1.
Step 1: UV radiation splits an oxygen molecule (O₂) into two oxygen atoms (O): O₂ + UV→2O
2.
Step 2: One of the oxygen atoms combines with another oxygen molecule (O₂) to form ozone (O₃)
O + O₂→ O₃
