The composition of ozone is O3 and the oxygen O2 present in

SUMMARY

The composition of ozone (O3) and oxygen (O2) in the atmosphere is a critical topic in atmospheric science. Despite O3 being heavier than O2, it is found in the stratosphere rather than at lower altitudes. This phenomenon occurs because gases in the atmosphere do not separate based on molar mass due to rapid mixing, particularly in the troposphere. The presence of ozone in the atmosphere primarily results from photochemical reactions involving ultraviolet (UV) radiation.

PREREQUISITES
  • Understanding of atmospheric layers, specifically the troposphere and stratosphere.
  • Knowledge of gas composition and behavior in the atmosphere.
  • Familiarity with photochemical reactions and their role in ozone formation.
  • Basic principles of molar mass and gas mixing dynamics.
NEXT STEPS
  • Research the process of ozone formation through photochemical reactions.
  • Study the differences between the troposphere and stratosphere regarding gas composition.
  • Explore the implications of ozone layer depletion and its environmental impact.
  • Learn about the role of ultraviolet (UV) radiation in atmospheric chemistry.
USEFUL FOR

Atmospheric scientists, environmental researchers, educators, and students interested in understanding the dynamics of ozone and its significance in the atmosphere.

the composition of ozone is O3 and the oxygen O2 present in atmosphere.considering the masses of O3 and O2 , the O3 is more heavier than O2 then also ozone is situated above the oxygen (O2) present in atmosphere. why is it so?

advanced thanks.

In general there is no separation of gases in the atmosphere due to their molar masses, mixing is way too fast (at least in troposphere).

Where does the ozone in atmosphere comes from?

actually the ozone(O3) is in stratosphere and O2 is in air OR atmosphere. though the O3 is more heavier than O2 then how O3 situated above O2 which has less mass then O3.
 


Seems like I have to repeat myself - twice.

First, in general there is no separation of gases due to their molar masses in atmosphere, so fact that ozone is heavier is irrelevant.

Second, please think about the question I asked, as the answer directly leads to the reason behind ozone being where it is - where does the ozone in atmosphere comes from?
