A neuron has an intracellular K+ concentration of 140 mM and an extracellular K+ concentration of 5 mM. If the membrane becomes selectively permeable to K+ only, and the equilibrium potential for K+ is calculated to be -85 mV, what would happen to the membrane potential if the extracellular K+ concentration suddenly increased to 15 mM?
