WebNov 29, 2024 · To derive the diffusion equation in one spacial dimension, we imagine a still liquid in a long pipe of constant cross sectional area. A small quantity of dye is placed in a cross section of the pipe and allowed to diffuse up and down the pipe. The dye diffuses from regions of higher concentration to regions of lower concentration. WebJul 28, 2024 · Graham's Law of Diffusion just bases the ratio of diffusion rates z on the reciprocal ratio of the square root of the molar masses M. If we normalize one molar mass to 1 and the diffusion rate of that gas to 1, then z* ∝ 1 √M *. Or more explicitly, with either gas having z and M not 1, zB zA = √ M A M B

Graham's law of diffusion derivation

WebJul 3, 2024 · Graham's law is a gas law which relates the rate of diffusion or effusion of a gas to its molar mass. Diffusion is the process of slowly mixing two gases together. Effusion is the process that occurs when a gas is permitted to escape its container through a … 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.
