Rate 1 is the rate of effusion for the first gas. (volume or number of moles per unit time). Rate 2 is the rate of effusion for the second gas. M 1 is the molar mass of gas 1 M 2 is the molar mass of gas 2. Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight.
This equation is known as Graham's law of effusion. The effusion rate for a gas depends directly on the average velocity of its particles. Thus, the faster the gas particles are moving, the more likely they are to pass through the effusion orifice.
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. For example, in a box with a microporous membrane containing a mixture of two gases, the lighter molecules will pass out of the container more rapidly than the heavier molecules, if the ...
Thomas Graham is known for his studies on the behavior of gases, which resulted in his formulation of two relationships, both since becoming known as "Graham's laws," the first regarding gas diffusion, [7] and the second regarding gas effusion. [8]
Graham's law of effusion = where: Rate 1 is the rate of effusion of the first gas. Rate 2 is the rate of effusion for the second gas. M 1 is the molar mass of gas 1 M ...

Graham's law This law states that the rate at which gas molecules diffuse is inversely proportional to the square root of the gas density at a constant temperature. Combined with Avogadro's law (i.e. since equal volumes have an equal number of molecules) this is the same as being inversely proportional to the root of the molecular weight.
