The equilibrium distribution of a molecule across a membrane depends on concentration and membrane potential. A charged molecule will respond to both components of the electrochemical gradient and will distribute accordingly. K+ ions for example, are at equilibrium across the plasma membrane even though they are 30-fold more concentrated inside the cell. the difference in concentration is balanced by the membrane potential, which is more negative on the inside. The membrane potential opposes the movement of cations to the outside of the cell.
