From the list of the following species, choose the appropriate binary mixture (group of two species) for each of the following questions.

Explain your answers.

(a) Consider liquid–vapor equilibrium at 1 bar.

(i) What binary mixture will have the largest positive deviations from ideality?
(ii) What binary mixture will have the largest negative deviations from ideality?

(b) What binary mixture will most closely follow the Lewis fugacity rule?

(c) What binary mixture is most likely to have its second cross-virial coeffi cient, B12, more negative than that of either of the pure species, B11 and B22?

(d) What binary mixture is most likely to have B12 = √B₁₁B₂₂ as its second cross-virial coeffi cient?
