A and B are mutually dissolved in the liquid phase and the solid phase. Some thermal properties of A and B are given by: Set that the liquid phase and the solid phases are ideal and have the same heat capacities. 2.1 Plot G(s)M vs. XB and G(l)M vs. XB at 1400K when GA(l)0 and GB(s)0 equal zero. 2.2 Plot G(s)M vs. XB and G(l)Mvs.XB at 1400K when GA(l)0 and GB(l)0 equal zero. 2.3 Plot the phase diagram with respect to XB. 2.4 Plot the curve of aAvs.XB with respect to pure solid A and the curve of aAvs. XB with respect to pure liquid A at 1400K. Please label the length of aA at XA=1 for each curve. 2.5 Plot the curve of aBvs.XB with respect to pure solid B and the curve of aAvs.XB with respect to pure liquid B at 1400K. Please label the length of aB at XB=1 for each curve
