1000 moles of 60% methanol and 40% water mixture at 80F and 1atm is heated. The following equilibrium data of methanol had been obtained. Please answer the questions below: a) At what temperature does it first begin to boil? What is the composition of the first bubble of vapour? [1.5 marks] b) At what temperature would it stop boiling (assume no material is removed)? What is the composition of the last liquid droplet? [1.5 marks] c) If the system is flashed at 166F, what is the fraction of liquid? [1.5 marks] d) When 70 mole\% has been vaporized, what is the temperature and what are the liquid and vapour composition? [1.5 marks] e) Calculate the relative volatility AB at 190F [1.5 marks]
