The volume of a liquid is increased isothermally. The molar volume of the liquid decreases from 30.25x10 m³/mol to 20.52x10 m³/mol during this process. The isothermal compressibility of the liquid is 10' Pa", which can be assumed to be independent of pressure. Calculate the molar Gibbs free energy of the liquid ------? a) 5730 J/mol b) 2450 J/mol c) 9730 J/mol d) 6530 J/mol
