The Molecular Diffusion (N_A) describes the dispersion of mass.  Diffusion explains the flux of molecules (liquid or gas) which cause a gradual mixing of different materials. Diffusive equilibrium is when the concentrations of all materials are equally distributed. This equation uses a R with units of (liter*atm / mol*K).  Molecular Diffusion is quantified as diffusive flux measured in units of mole/(time x area).
