Question

Give balanced equations for formation of ozone molecules from oxygen molecules. What type of reaction takes place, during the formation.

Answer 1

The reaction that takes place during the formation is photolysis or photo dissociation. Highly energetic UV from the sun break the O2 molecule in two atoms. Highly reactive O atom reacts with O2molecule to from ozone O₃

\[\ce{O2->[U.V][light][O] + [O]}\]

[O] + O2 → O₃ [ozone]
