Text Solution

Verified by Experts

The formation of ozone in the stratosphere takes place in two steps. In the first step, ultraviolet radiation coming from the sun have sufficient energy to split dioxygen into two oxygen atoms In the second step, the oxygen atoms react with more of dioxygen to form ozone
