The exchange rate of a gas across a fluid membrane can be determined by using this law together with Graham's law.

* Graham's law

* Graham's law states that the rate at which gas molecules diffuse is inversely proportional to the square root of its density.

Graham's law, known as Graham's law of effusion, was formulated by Scottish physical chemist Thomas Graham in 1846.

Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight.

A complete theoretical explanation of Graham's law was provided years later by the kinetic theory of gases.

Graham's law provides a basis for separating isotopes by diffusion — a method that came to play a crucial role in the development of the atomic bomb.

Graham's law is most accurate for molecular effusion which involves the movement of one gas at a time through a hole.

Graham's law for diffusion could thus be understood as a consequence of the molecular kinetic energies being equal at the same temperature.

According to Graham's law, the rate at which gases effuse ( i. e., how many molecules pass through the hole per second ) is dependent on their molecular weight ; gases with a lower molecular weight effuse more quickly than gases with a higher molecular weight.

A figure of Graham's law of effusion linked below shows the rate of effusion ( the rate at which the gas is transferred across the barrier through the pin hole ) is inversely proportional to the square root of the mass of the gas molecules.

This result is useful for many applications such as Graham's law of effusion, which provides a method for enriching uranium.

Gaseous diffusion is based on Graham's law, which states that the rate of effusion of a gas is inversely proportional to the square root of its molecular mass.

Graham's research on the diffusion of gases was triggered by his reading about the observation of German chemist Johann Döbereiner that hydrogen gas diffused out of a small crack in a glass bottle faster than the surrounding air diffused in to replace it.
