Question

what happens during the first step of ozone formation in atmosphere

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 first step, solar ultraviolet

radiation breaks apart one oxygen molecule (O2) to produce

two oxygen atoms (2 O) (see Figure Q2-1). In the second step,

each of these highly reactive atoms combines with an oxygen

molecule to produce an ozone molecule (O3). These reactions

occur continually whenever solar ultraviolet radiation is present

in the stratosphere. As a result, the largest ozone production

occurs in the tropical stratosphere.

Answer 2

oxygen is naturally produced in the stratosphere by two step reactive process in the first step the solar ultraviolet radiation breaks apart an oxygen molecules to form two separate oxygen atoms in the overall process these oxygen molecules and sunlight react to form two ozone molecules
