Question: A binary mixture obeys a simple one-term equation for excess Gibbs energy, G E = Ax 1 x 2 , where A is a function

A binary mixture obeys a simple one-term equation for excess Gibbs energy, G^E = Ax₁x₂, where A is a function of temperature: A = 2930 + 5.02E5/T(K) J/mol.

(a) Does this system exhibit partial immiscibility? If so, over what temperature range?

(b) Suppose component 1 has a normal boiling temperature of 310 K, and component 2 has a normal boiling temperature of 345 K. The enthalpies of vaporization are equal, both being 4475 cal/mol. Sketch a qualitatively correct T-x-y diagram including all LLE,VLE behavior at 1 bar.
