Question

Explain the formation and depletion of the ozone layer with the chemical reaction

Answer 1

Stratospheric ozone is formed naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up 21% of the atmosphere. ... In the second step, each of these highly reactive atoms combines with an oxygen molecule to produce an ozone molecule (O3).

When ultraviolet light waves (UV) strike CFC* (CFCl3) molecules in the upper atmosphere, a carbon-chlorine bond breaks, producing a chlorine (Cl) atom. The chlorine atom then reacts with an ozone (O3) molecule breaking it apart and so destroying the ozone.

Cl + O3 = ClO + O2

Answer 2

Answer:

ozone is naturally produced in the stratosphere by a two-step reactive process. in the first step. solar

ultraviolet radiation (sunlight) breaks apart and oxygen atoms. in the overall process, 3 oxygen molecules plus sunlight react to form to ozone molecules.
