Homer asked:
I asked my professor Which force governs diffusion and He didn't know.
If you reduce the problem to the basics then you find it is all down to the particles following a random walk. Essentially there is no driving force to diffusion only the force which causes random walks which is system specific e.g. particle collisions, electromagnetic etc.
