Question

O+O-O2 it is stable then why it is reacting with another O to form O3

Answer 1

Answer:

O2 doesn't actually react on it's own to form O3..

This reaction takes place due to UV rays.. The UV rays in the atmosphere above split O2 to free O atoms.. Since these are unstable so the free O react with O2 to form O3..

Hope it helps.....!
