Diffusion coefficient (Mass diffusivity) for liquids
Description
Diffusivity or diffusion coefficient is a proportionality constant between the molar flux due to molecular diffusion and the gradient in the concentration of the species (or the driving force for diffusion). There is an approximate dependence of the diffusion coefficient on temperature in liquids.
