Consider a binary liquid mixture of 40 mole % 1-propanol (1) in water (2) at 25°C and 100 bar. For this system, the Henry’s law constant for 1-propanol has been estimated to be:

The density of pure liquid 1-propanol is 0.80 g/cm3.

(a) As best as you can, determine the fugacity of 1-propanol in the liquid mixture,

(b) Are the like interactions or the unlike interactions stronger? Explain.
