The velocity of this process is related to the gradients of chemical potential and of the log of activity in the Maxwell-Stefan model.
The velocity of this process is related to the gradients of chemical potential and of the log of activity in the Maxwell-Stefan model. The constant associated with this quantity equals the Boltzmann constant times temperature times drift velocity divided by applied force. That constant is also proportional to mean thermal speed and mean free path in a law that multiplies that constant by the derivative of concentration with respect to position, which is Fick's Law. Name this process involving a larger opening than the quantity usually addressed by Graham's Law in which the random motion of particles leads them to spread out.
