Question

Write in details about the production of stratospheric ozone?

Answer 1

Ozone is naturally produced in the stratosphere by a two-step reactive process. In the first step, solar ultraviolet radiation (sunlight) breaks apart an oxygen molecule to form two separate oxygen atoms. In the second step, each atom then undergoes a binding collision with another oxygen molecule to form an ozone molecule. In the overall process, three oxygen molecules plus sunlight react to form two ozone molecules. Overall reaction :

O₂ + ℎν_uv → 2$O^{.}$

$O^{.}$ + O₂ ↔ O₃
