One mole of solid Cr2O3 at 2500 K is dissolved in a large volume of a liquid Raoultian solution of Al2O3 and Cr2O3 in which xCr2O3 = 0.2 and which is also at 2500 K. Calculate the changes in enthalpy and entropy caused by the addition. The normal melting temperature of Cr2O3 is 2538 K; assume that the ΔSm,Al2O3 = ΔSm,Cr2O3 [= 46.25 J/(mol.K)].
Any help would be appreciated.
