Problem 1: Calculate Cp298 for AlF3. Given: Cp298 for Al=14.6J,Cp298 for F=21.3J Problem 2: Calculate the change in (HrH298) for Cu Copper has phase transformation at 1357K (Melting point) and 2835K (Boiling Point), and the heat of fusion is 13.05KJ/mol and heat of evaporation is 300.3KJ/mol. From TSIM and HSC we know: CP0(s)=5.32+1.62103T+0.07105T2J/ mole ;Hfus0=13,050J/mole at 1357.6K CP0(l)=7.8;Hvap0=300,300J/ mole at 2836K
