WebJul 29, 2024 · Graham’s law of diffusion is the relationship between a gas’s rate of diffusion or effusion and its molecular weight. The law of diffusion’s basic tenet is that any gas’s rate of diffusion, at any given temperature and pressure, is inversely proportional to the square root of its density.
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 = … orchha footballWebGraham also performed equal countercurrent experiments in 1863, using a long closed-tube apparatus he devised.
