The permeability of a membrane affects the rate of diffusion.Diffusion rate increases as membrane permeability increases. Changes in temperatureand pressure values also affect the diffusion of substances. Pressure plays an importantrole in the diffusion of gases as gases diffuse from a region of ...
Graham's law defines the rate of diffusion of the gas. The rate of diffusion of a gas is inversely proportional to the square root of the mass of the gas. The expression of the law is: r∝1M Here: r is the rate of diffusion of the gas. ...
The rate of approach to the steady state in a convection-free two-bulb thermal diffusion experiment is treated in a more rigorous manner than previously available, in order that reliable ordinary diffusion coefficients may be derived from thermal diffusion measurements. The final results are of the...
