The excess free energy of mixing for an A-B solution is desc

The excess free energy of mixing for an A-B solution is described by the following equation: ΔGmix(XS) = XAXB (8750 XA + 9500 XB) (1 – T/3900) [J/mol]. Answer the remainder of the questions of this homework for this solution at XB=0.450 and T=975K. Is this a regular solution?What was the IDEAL contribution to ΔGmix [J/mol]? (What does ideal contribution mean?)What was the EXCESS contribution to ΔSmix? [J/molK] (What does excess contribution mean?)What was ΔSmix [J/molK]? (Is it 5.7211)What was ΔGmix [J/mol]? (Is it -5578.16)What was ΔVmix [cm^3/mol]?Please Upload work.Answer
