Graham's law of diffusion derivation
WebHow to derive expressions for diffusion-controlled current vs. time:402 1. Solve Fick’s Second Law to get C O (x,t), and in the process of doing this, you will use boundary conditions that “customize” the solution for the particular experiment of interest: 3. Calculate the time-dependent diffusion-limited current: i = nFAJ O (0, t) 2. Graham's law of effusion (also called Graham's law of diffusion) was formulated by Scottish physical chemist Thomas Graham in 1848. Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles. This formula is stated as: ,

WebGraham’s law of effusion: rates of diffusion and effusion of gases are inversely proportional to the square roots of their molecular masses mean free path: average distance a molecule travels between collisions rate of diffusion: amount of gas diffusing through a given area over a given time WebThe rates of effusion of gases are inversely proportional to the square roots of their densities or to the square roots of their atoms/molecules’ masses (Graham’s law). Key Equations rate of diffusion = amount of gas passing through an area unit of time rate of diffusion = amount of gas passing through an area unit of time
