Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. Effusion refers to the movement of gas particles through a small hole. Graham's Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.

13 cze 2023 · Why is the diffusion equation the same as the effusion equation, but for a different reason? In simple diffusion, 2 gases move in opposite directions through a medium with the same pressure everywhere.
9 gru 2019 · Graham's law expresses the relationship between the rate of effusion or diffusion of a gas and that gas's molar mass. Diffusion describes the spreading of a gas throughout a volume or second gas and effusion describes the movement of a gas through a tiny hole into an open chamber.
26 sie 2023 · When this process is restricted to passage of molecules through very small openings in a physical barrier, the process is called effusion. If a mixture of gases is placed in a container with porous walls, the gases effuse through the small openings in the walls.
Graham's law calculates the rate of diffusion or effusion and molar mass of gases. The equation of Graham's law is: rate 1 / rate 2 = √ (mass 2 / mass 1) rate 1 and rate 2 - Rates of effusion or diffusion of Gas 1 and 2, respectively; mass 1 and mass 2 - Molar masses of Gas 1 and 2, respectively.
9.6 Effusion and Diffusion of Gases. Learning Objectives. By the end of this section, you will be able to: Define and explain effusion and diffusion. State Graham’s law and use it to compute relevant gas properties.
Starting with the definition of rate of effusion and Graham’s finding relating rate and molar mass, show how to derive the Graham’s law equation, relating the relative rates of effusion for two gases to their molecular masses.
