WebEffusion is the movement of gas molecules from one container to another through a tiny hole. Rates of effusion can be compared at the same temperature using Graham’s law. Diffusion is the movement of gas molecules through one or more other types of gas via random molecular motion. WebGraham's Law Equation. The 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. philly truce incWebGraham'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 gas. tsc hrms
