WebJul 28, 2024 · Graham's Law of Diffusion just bases the ratio of diffusion rates z on the reciprocal ratio of the square root of the molar masses M. If we normalize one molar mass to 1 and the diffusion rate of that gas to 1, then z* ∝ 1 √M *. Or more explicitly, with either gas having z and M not 1, zB zA = √ M A M B 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.
