If the standard enthalpy change and standard entropy change for the dissolution of borax at 298 K is 60 kJ and 150 J K-1 calculate the standard Gibbs free energy change value in kJ at that temperature. Does the value for standard enthalpy change suggest that the solvation of borax is endothermic or exothermic, and why is the result consistent with the observation that less borax is dissolved at lower temperatures?
