Graham'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: , WebGraham's law of diffusion (also known as Graham's law of effusion) states that the rate of effusion a gas is inversely proportional to the square root of its molar mass.

WebGraham’s law of effusion: rates of diffusion and effusion of gases are inversely proportional to the square roots of their molecular masses mean free path: average distance a molecule travels between collisions rate of diffusion: amount of gas diffusing through a given area over a given time WebThe equation for graham's law is: R a t e A R a t e B = M B M A. Where, M A and Rate A are the molar mass and rate of effusion/diffusion of gas, A respectively. M B and Rate B are the respective molar mass and rate of effusion/diffusion of gas, B. What this basically tells us is the ratio of rates based on their masses.
