Chemistry

If a cell with a resting membrane potential of -70 mV is treatedso that the resting membrane potential is at the equilibriumpotential of K+, and then the permeability of the membrane for allions is returned to normal: why WONT K+ move into the cell acrossthe cell membrane until the resting membrane potential is restoredbut Na+ will?
