Diffusion and the second law of thermodynamics are both explained by statistical mechanics.

Any standard textbook on statistical mechanics will cover the second law, and googling for "diffusion statistical mechanics" will find many good papers on diffusion. Unfortunately there's a fair amount of math involved.
