WEBDiffusion 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.

WEBApr 12, 2024 · 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.

Effusion - Wikipedia
https://en.wikipedia.org/wiki/Effusion
WEBScottish chemist Thomas Graham (1805–1869) found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the mass of its particles. In other words, the ratio of the rates of effusion of two gases at the same temperature and pressure is given by the inverse ratio of the square roots of the masses of ...

WEBJun 13, 2023 · Effusion. Effusion is the movement of a gas through a tiny hole into a vacuum. We want to know the rate of effusion, which is how much gas moves through the hole per unit time. We assume that the gas particles don't bump into each other while they move through the hole (this means it's a narrow hole in a thin wall).
