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. WebGraham's law states that the rate of diffusion for a gas is inversely proportional to the square root of its molar mass. Now, let's break that down into what exactly that means. Okay. So we, let's define diffusion because the word effusion comes from the word diffusion. Okay.

"WebDiffusion is always along chemical potential gradient! Diffusion stops when chemical potential of all species everywhere are same. In most cases, chemical potential increases with increasing concentration, so it is convenient to express diffusion in term of concentration. Now lets consider Interstitial diffusion vs. Substitutional diffusion: " - Graham's law of diffusion derivation

Graham's law of diffusion derivation

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 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.
