Problem 11.1: A vapor mixture of acetone (1) and nitromethane (2) (y1 = 0.7) initially at P = 1 bar and 110 °C is to be liquefied by compression under constant temperature.
a) At what pressure does the system fully become a liquid?
b) Calculate the composition of the last bubble that condenses.
c) What is the fugacity of nitromethane in the liquid when the system is at the conditions of part (a)?
Assume that the system behaves according to Raoult's law. The saturation pressures of pure acetone and nitromethane at 110 °C are 463 kPa, and 132.4 kPa respectively.
