Subject Editor A. J. Ricco. 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
