The concentration of K+ ions in the intracellular fluid of a nerve cell is approximately 361.669 mM, but in the extracellular fluid the K+ concentration is 20.15 mM. Given that the electric potential difference inside and outside the cell is given by φ (inside) - φ(outside) = –70.0 mV, calculate the Gibbs energy change (to the zeroth decimal place in Joules) for the transfer of 1.00 mol of K+ ion against the concentration gradient at 37.8oC.
