A general model for this process in multicomponent systems that allows for negative constants of proportionality was discovered independently by Maxwell and Stefan.
A general model for this process in multicomponent systems that allows for negative constants of proportionality was discovered independently by Maxwell and Stefan. One statement referring to this phenomenon sets its flux proportional to the negative position derivative of a certain quantity; the other sets the time derivative of concentration proportional to the second derivative of that quantity; those are Fick's laws of this process. A "facilitated" form occurs in the cell when membranes proteins form channels to help bulky molecules do this. For 10 points, name this process by which particles move randomly down a concentration gradient.
