Diffusion can be defined as mixing of two or more substances or the net motion of a substance from an area of high concentration to an area of low concentration.

Diffusion Coefficient can be defined as a factor of proportionality representing the amount of substance diffusing across a unit area through a unit concentration gradient in unit time.

A number of correlations have been proposed for predicting the diffusion coefficient for a binary mixture of solute A in solvent B (e.g. propane in chlorobenzene). The Wilke-Chang method estimates this coefficient for dilute solutions.
