Graham's law of diffusion/effusion
WebMar 14, 2024 · Graham's law of diffusion (or Graham's law of effusion) is a law that expresses the relationship between the rate of diffusion or effusion to molar masses of particles. This empirical law was stated by Scottish chemist Thomas Graham in 1848. He established the relationship through experiments. Table of Contents WebGraham's law of effusion can be demonstrated with the apparatus shown below. A thick-walled filter flask is evacuated with a vacuum pump. A syringe is filled with 25 mL of gas and the time required for the gas to …

WebExplanation: Graham's law states that the rate of effusion of a gas is inversely propertional to the square root of the density of the gas. Since equal volumes of gas at the same temperature and pressure contain equal numbers of gas molecules, the rate of effusion is also inversely proportional to the square root of the molecular weight of the ...
