please answer as detailed as possible

Question 2: A liquid alcohol mixture is to be fed to a distillation tower at 101.32kPa and has the following composition: methyl alcohol (XA = 0.30), ethyl alcohol (xp = 0.20), n-propyl alcohol (Xc = 0.15) and n-butyl alcohol (xp = 0.35). Calculate the following assuming that the mixture follows Raoult's Law. - a) The boiling point of the mixture and the composition of the vapour in equilibrium b) The dew point and composition of the liquid in equilibrium c) The temperature and composition of both phases when 60% of the feed is vapourised in a flash distillation. The vapour pressure data for each alcohol is given below.
