Question

what do you mean by the ozone layer depletion? write down the reaction involved in ozone layer depletion

Answer 1

Ozone depletion describes two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.[1] The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events.



CFCl3 + UV Light ==> CFCl2 + Cl
Cl + O3 ==> ClO + O2
ClO + O ==> Cl + O2

The free chlorine atom is then free to attack another ozone molecule

Cl + O3 ==> ClO + O2
ClO + O ==> Cl + O2

and again ...

Cl + O3 ==> ClO + O2
ClO + O ==> Cl + O2

$\bold{Hey \: mate \: here \: is \:your \: ANSWER}$

Ozone layer depletion means decreasing in the concentration of ozone gas in the atmosphere by some gases such as CFC's and HCFC's . These gases are used in refrigerators. It is also broken down by UV rays of sun and also get formed by it.
