If at least one of the phases is not practically infinite in extent and the solute is neither consumed nor synthesized, then the process will “run down” to equilibrium as the passive flux acts to equalize the chemical potentials on each side of the barrier.
If the solute is consumed or synthesized on one side of the membrane, then a nonequilibrium steady state can be achieved, such that the flux across the membrane equals the rate of consumption or synthesis.
