Question

explain the formation of ozone in the higher levels of atmosphere giving revent chemical equation

Answer 1

Ozone , O3 , contain 3 atoms of oxygen, it is deadly poisnous for animals, but in the upper layer of atmosphere, it act as a shield by protecting us from UV (ultravoilet) rays which comes from sun. these rays can cause disease like skin-cancer.

FORMATION OF OZONE:when oxygen reaches the uppermost layer of atmosphere , it reacts with UV rays which split it into free-oxygen atom, then these single oxygen atom combine with O2 to form ozoneO2 ----uv--- O + O O + O2 ------- O3
