WebJul 3, 2024 · Solution: Graham's Law can be expressed as: r X (MM X) 1/2 = r Y (MM Y) 1/2. where. r X = rate of effusion/diffusion of Gas X. MM X = molar mass of Gas X. r Y = rate of effusion/diffusion of Gas Y. MM Y = molar mass of Gas Y. We want to know how much faster or slower Gas Y effuses compared to Gas X. http://chemed.chem.purdue.edu/genchem/history/graham.html
