Figure 4 :Panel A : variation of the temperature scaled excess free energy against the composition X of a binary fluid mixture. Panel B : Phase diagram of a binary fluid. The continous curve is the locus of the minima of panel A (binodal curve, ∂GEXC(X)/∂X=0), while the dashed curve is the locus of the inflexion points (spinodal curve, ∂GEXC(X)/∂X2=0). To is the composition-dependent temperature at which phase separation takes place
