The change in diffusing molecules over time is called the rate of diffusion. The diffusion rate of a gas is inverse to the square root of the volume (density). Hence, the rate of diffusion formula is: rate of diffusion \[\alpha \frac{1}{\sqrt{density}}\]

13 lut 2023 · Diffusion can be described as the random movement of particles through space, usually due to a concentration gradient. Diffusion is a spontaneous process and is a result of the random thermal motions between two particles. The diffusion coefficient (\ (D\)) can be solved for with Fick’s laws of diffusion, which are broken up into two laws.
Graham’s law is an empirical relationship that states that the ratio of the rates of diffusion or effusion of two gases is the square root of the inverse ratio of their molar masses.
