Gasseous diffusion wiki
WebDiffusion is the movement of molecules from a region of higher concentration to a region of lower concentration. The rate at which molecules diffuse can be determined by the relationship of molecular weight and that rate of diffusion through a membrane. WebGas diffusion involves random molecular movement from areas of high partial pressure to areas of low partial pressure. The rate of diffusion depends on the partial pressure (or tension) difference between each area. The partial pressure (P) of a gas in a mixture is the pressure that a given gas would exert if it alone occupied the space.
