Flory-Huggin's Theory

I've got a problem here which I am supposed to solve but I am not able to get a mathematical answer to, I hope to be able to seek some help here.



The question is:



Show that the Flory-Huggin's equation always shows a negative deviation from Raoult's Law.



Would appreciate any help rendered. Thanks.

I'm not sure where it is that you are stuck in your derivation. Prausnitz has a few quick lines in his "Molecular Thermodynamics of Fluid-Phase Equilibria" (1969, Section 7.7) showing the inequality. The library should have a copy as the text was a classic. Post again if you need more help.
