Graham's law of diffusion of gases

WebGraham’s law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its density or the square root of its molar mass at a given temperature and pressure. This means that lighter gas effuses or diffuses easily; whereas, heavier gas molecules take time to effuse or diffuse. WebApplying Graham’s Law to Rates of Effusion Calculate the ratio of the rate of effusion of hydrogen to the rate of effusion of oxygen. Solution From Graham’s law, we have: rate of effusion of hydrogen rate of effusion of oxygen = 32 g mol −1 2 g mol −1 = 16 1 = 4 1 Hydrogen effuses four times as rapidly as oxygen.
