WebGraham's law states that the rate of diffusion for a gas is inversely proportional to the square root of its molar mass. Now, let's break that down into what exactly that means. Okay. So we, let's define diffusion because the word effusion comes from the word diffusion. Okay. So diffusion means the movement of one material through another. 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.
