Rate of Diffusion

Definition

The rate of diffusion refers to how quickly molecules move from an area of high concentration to an area of low concentration. It is influenced by factors such as temperature, concentration gradient, and the size and nature of the molecules involved.

Concentration Gradient:

The difference in concentration between two areas, which affects the rate at which molecules diffuse.

Surface Area-to-Volume Ratio: The ratio between the surface area and volume of an object or cell. It influences the efficiency of diffusion because more surface area allows for greater exchange of molecules.

Permeability: Refers to how easily molecules can pass through a membrane or barrier. Higher permeability leads to faster diffusion rates.
