What is the most important function of stratospheric ozone?
Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. This is typically regarded as ‘good’ ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth’s surface.
Why is o3 unstable?
This is because oxygen decomposes in Ozone and then the Heat is liberated. Adding to this, Ozone is known to consist of 3 molecules of oxygen and is in an unstable state and is known to give out one molecule of oxygen for restoring a diatomic state.
Is O2 more stable than O3?
Hint: The ozone consists of three atoms of oxygen and is in an unstable state. It decomposes into O2 molecule with liberation of an enormous amount of heat. This heat is released in the atmosphere. Thus, the formation of oxygen molecules is thermodynamically more stable than ozone molecules.
How is O3 thermodynamically unstable?
Ozone is thermodynamically less stable than oxygen because its decomposition into oxygen results in the liberation of heat. Ozone consists of three molecules of oxygen and thus in this its in unstable state so in order to get stable it gives up its one molecule of oxygen to restore diatomic state.
Can you breathe ozone?
When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.
Is O3 breathable?
Often called “smog,” ozone is harmful to breathe. The ozone layer found high in the upper atmosphere (the stratosphere) shields us from much of the sun’s ultraviolet radiation. However, ozone air pollution at ground level where we can breathe it (in the troposphere) causes serious health problems.
Why is O3 lighter than O2?
Because O3 forms in the upper atmosphere due to ultraviolet light and cosmic rays hitting O2 molecules. Also because once formed, O3 is thermodynamically unstable and reconfigures to O2 faster than it “falls” to lower altitudes. Originally Answered: Ozone is heavier than Oxygen, but why it stay in the higher sky?
How do you make O3?
Ozone (O3) is created when diatomic oxygen (O2) is exposed to an electrical field or ultraviolet (UV) light. Exposure to these high levels of energy causes a portion of the diatomic oxygen molecules to split into individual oxygen atoms. These free oxygen atoms combine with diatomic oxygen molecules to form ozone.
How do I know if my air purifier emits ozone?
The easiest way to tell if your air purifier emits ozone is that it smells like antiseptic. Other ways include a blue light shining from it, and the surfaces around the air purifier being extra dusty.
How long does it take for ozone to dissipate in a room?
30 min to 4 hrs
