Graham's law of diffusion derivation

WebFeb 6, 2024 · Graham’s law of diffusion states that, at constant temperature and pressure, gaseous molecules or gaseous atoms having lower molecular mass move faster than molecules having higher molecular mass. Graham’s law of diffusion states that, the rate of diffusion is inversely proportional to the square root of the molecular mass of the gas. 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.

WebFeb 12, 2024 · For a gas, the rate at which diffusion occurs is proportional to the square root of the density of the gas. The density of a gas is equal to the mass of the gas divided by the volume of the gas. If the volume is held constant one gas is compared with another with another, R 2 R 1 = M 1 M 2. where R is the rate of diffusion in mol/s and M is the ... WebDiffusion. 1. Diffusion refers to the process by which molecules of matters move from high concentration towards the low concentration. 2. For example, when a sugar cube is dropped in a glass of water the particles of sugar mixes up in the water as they move from higher concentration of sugar cube towards the lower concentration of water.
