Ozone is formed by the reaction of a oxygen molecule with a oxygen atom due to high UV radiation
3O_2rightleftharpoons2O_33O22O3
process is as
O_2->2OO22O(1)due to the energy of UVUVrays
2O_2+2Orightleftharpoons2O_32O2+2O2O3(2)
(1)-(2)
3O_2rightleftharpoons2O_33O22O3
It is imprtant for the life at higher altitudes as the it absorbs the UV rays and dont allow them to fall on earth
at lower altitudes ozone is a harmful gas to the life on earth
