WebGraham's law of effusion (also called Graham's law of diffusion) was formulated by Scottish physical chemist Thomas Graham in 1848. Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles. This formula is stated as: =, where: Rate 1 is the rate of effusion for the first gas.
WebJul 29, 2024 · Answer: According to Graham’s Law, the square root of a gas’s molar mass has an inverse relationship with the rate of diffusion or effusion of that gas. The equation for this law is shown below. r is inverse proportional to square root of M.
