Different concentrations of ions on either side of a cell membrane constitute a concentration cell, which is described by the Nernst equation given below. A cell must expend energy to maintain this concentration gradient by moving ions from one side of the membrane to the other. How much energy must be expended to transport 1 mole of sodium ions across a membrane when the sodium ion concentration is 0.10 M on one side of the membrane and 0.010 M on the other side, and the temperature is 37 $\circ$ C (body temperature)?
(Given: , = -2.71 V; F = 96,485 C; 1 J = 1 C V; R = 8.315 J / (mol K))
E = E $\circ$ - InQ
