Question

Nitrogen oxides released in the stratosphere cause ozone depletion due to
A) Catalyzing conversion of ozone to oxygen
B) Binding ozone
C) Reacting with ozone
D) All of the above

Answer 1

Hint: In nature the bacteria present in the soil and the oceans break down nitrogen-containing compounds and release nitrous oxide. The nitrous oxide is stable when emitted at the ground level but breaks down when it reaches to the stratosphere to form other gases called as nitrogen oxides that triggers the ozone-destroying reactions.

Complete answer:
The nitrogen oxide affects both the ozone layer and global warming when it is released into the atmosphere.
The ozone depletion means that the destruction of ozone exceeds the creation of O3. When it is present together in the stratosphere the chlorine and the ozone react quickly to produce the chlorine oxide.
The ozone layer depletion is the reduction of the amount of ozone in the stratosphere.
The chlorine atoms react with the Ozone and start a chemical cycle that destroys the good ozone in that area.
Therefore, the correct answer is option C.

Additional information:
The oxides of the nitrogen are the mixture of gases that are composed of the nitrogen and oxygen. The most toxicologically significant compounds are the nitric oxide and the nitrogen dioxide. Other gases that belong to this group are nitrogen monoxide and nitrogen pentoxide.
The nitrogen oxides are produced during the process of combustion, apart from the nitrogen compounds in the fuel but it is mostly by the direct combination of the atmospheric oxygen and the nitrogen in flames. The nitrogen oxides are produced naturally by lightning.

Note:
The chlorofluorocarbons and other halogenated ozone-depleting substances are responsible for the man made chemical ozone depletion. The overall amount of the effective halogens for example chlorine and bromine in the stratosphere can be calculated and also are known as the equivalent effective stratospheric chlorine.
Human activities cause the emission of the halogen source gases that contain the chlorine and the bromine atoms. These emissions into the atmosphere lead to stratospheric ozone depletion.
