Question

What is the mechanism of the natural dynamic equilibrium of stratospheric ozone?

Answer 1

When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozonemolecules. ... ODS that release chlorine include chlorofluorocarbons. Since they are not destroyed in the lower atmosphere, CFCs drift into the upper atmosphere where, given suitable conditions, they break down ozone.

Answer 2

Answer:

A system is said to be in mechanical equilibrium

when there are no unbalanced forces within the

system and between the system and its surround-

ings.

OR

A system is said to be in mechanical equilibrium

when the pressure in the system is the same

throughout and does not change with time.

Note: The constituents of a system, atoms, molecules,

ions, etc, are never at rest. Within a system, even in the

condition of equilibrium, statistical fluctuations do occur,

but the time of observation is usually very large so that

these fluctuations can be ignored.]
