Statement II: Ozone is mainly concentrated in stratosphere. (True)
Both the statements are individually true but Statement II is not the correct explanation of Statement I.
– The ozone layer, where most atmospheric ozone is found, is located primarily in the stratosphere, about 15-35 km above the Earth’s surface.
– The location of ozone in the stratosphere is due to its formation process, which involves the photolysis of oxygen molecules (O2) by UV radiation, followed by the combination of resulting oxygen atoms with O2. This process is most efficient in the stratosphere. However, this does not explain *why* the molecule itself has three atoms. The fact that it is tri-atomic is inherent to its chemical form, not dependent on its location.
