The infinite-dilution activity coefficients for the 1-butanol (1) + p-xylene (2) mixture at 333.15 K are Ý₁ = 7.2360 and Ý₂ = 4.9720 (Prasad, 1998). Will the 2-parameter Mar gules equation predict a miscibility gap for this system at this temperature? If so, what is the composition of the equilibrium phases?
