Consider a binary mixture of species a and b that results in two coexisting liquids (a and ß) at 298.15 K and 1 bar. The mixture is well-described by a one-constant (also known as two-suffix) Margules equation ex 9 RT = 3.127xaxb The ideal-gas constant R = 8.3145 J/(mol K) Obtain general expressions for both species a and b that define the conditions for phase equilibrium. The expressions can contain constants, temperature, pressure, and compositions. (Note: If you do not obtain a result for this part and need one for subsequent parts, please use (x)² = 0.73244 exp(Ar) x = 0.003786 exp(A(x)²)
