The distribution of Na* ions across a typical biological membrane is 10 mmol/dm³ nside the cell, and 140 mmol/dm³ outside the cell. At equilibrium, the concentrations across the membrane are equal. What is the Gibbs energy difference across the membrane at 37°C? The stated difference in concentration MUST be maintained by coupling to reactions that have at least your calculated difference of Gibbs energy. Ans: 6.8 kJ/mol
