Question

The process of separation of a mixture of gases by taking advantage of the difference in their rates of diffusion is known as:
Options
A.Distillation
B.Adsorption
C.Atmolysis
D.All of the above

Answer 1

The change in the amount of diffusing molecules over time, $\dfrac{{dn}}{{dt}}$, is the rate of diffusion. Since the concentration gradient affects the net movement of diffusing molecules, the rate of diffusion is proportional to the concentration gradient $\dfrac{{dC}}{{dx}}$ across the membrane.

Complete answer:
Distillation, also known as classical distillation, is the mechanism of selectively boiling and condensation to separate the components or substances in a liquid mixture. The heating of solid materials to produce gaseous compounds is known as dry distillation. Purification of alcohol, desalination, crude oil refining, and the production of liquefied gases from air are all examples of distillation's applications.
Adsorption is a phenomenon in which substance (adsorbate) moves from a gas or liquid phase to a solid or liquid condensed phase and forms a superficial monomolecular coating (substrate). The adhesion of electrons, ions, or molecules from a gas, liquid, or dissolved solid to a surface is known as adsorption. This procedure forms an adsorbate layer on the adsorbent's surface. A fluid is dissolved by or permeates a liquid or solid in this phase, as opposed to absorption, in which a fluid is dissolved by or permeates a liquid or solid.
Atmolysis is the process of separating gases via the porous septum using varying rates of fusion. Allowing gases to disperse through the walls of a porous membrane affects the isolation. Graham's Law is used to calculate gas diffusion rates. Graham's Law states that a gaseous substance's rate of diffusion is inversely proportional to its molar mass squared. That is a direct result of gaseous molecules having the same kinetic energy at the same temperature. This approach is used to separate a mixture of gases and is dependent on diffusion speeds. It aids in the separation of the two uranium isotopes.

Hence the correct option is C .
