1 mole of Cr is added to a large quantity of Cr-Fe melt (solution). The temperature of the solid and the melt is 1600°C and XFe = 0.8. Assuming Raoultian behaviour, what are the enthalpy and entropy changes in the solution? The enthalpy of fusion of Cr is 21,000J/mol at it's melting temperature, 1900 C.
