The infinite dilution activity coefficients for the methanol (1) + n-heptane (2) mixture at 30C are

Question:

The infinite dilution activity coefficients for the methanol (1) + n-heptane (2) mixture at 30°C are Ý₁ = 84.20 (Wobst et al., 1992) and Ý₂ = 35.10 (Gmehling et al., 1986). You know that this system shows a miscibility gap at this temperature (x₁^a = .167; x₁^β = .884) (Sorensen and Arlt,1979). Will the 2-parameter Margules equation predict a miscibility gap for this system? If so, what is the composition of the equilibrium phases and how do they compare with the experimental data?
