Question

Explain atmolysis.

Answer 1

Hint: The term atmolysis denotes the process of separation of two gases based on their rates of diffusion due to differences in their densities. It is used for the separation of isotopes and gaseous mixtures.

Complete answer:
Atmolysis is defined as the method of separation of gases via different rates of fusion through the porous septum. The separation is affected by allowing the gases to diffuse through the walls of a porous membrane.
Rates of diffusion of gases are based on Graham’s Law.
Graham’s Law states that the rate of diffusion of a gaseous substance is inversely proportional to the square root of its molar mass.
It is a direct consequence of the fact that gaseous molecules at the same temperature have the same kinetic energy.
This method is based on rates of diffusion and is used for the separation of a mixture of gases. It helps separate the two isotopes of uranium.
The diffusion process here is also proportional to the square root of its vapor density. It is deployed for the separation of gaseous mixtures. The physical states are changed from liquid to vapor state then the process of separation of gaseous mixtures takes place.

So, the correct answer is Option A.

Note: The atmolysis process gets the advantage of the different rates of diffusion due to which they are separated easily. Also, the mixture is kept in a vacuum in a vessel of a porous material such as graphite and then separated through an atomizer.
