a) The lab technician in food industry is carrying out the distillation process to separate butyl alcohol and water. Water and butyl alcohol form an azeotrope mixture with the composition of 28.4 mol% and 71.6 mol% of water that boils at 92.4 "C at 1 atm. Butyl alcohol boils at 117.8 'C while water at 100 "C at the same pressure. Sketch and label the boiling point composition phase diagram for the mixture. State the type deviation based on Raoult's Law. Identify the first distillate and residue if 75% butyl alcohol is distilled. Justify your answer. (10 Marks) b) Discuss three (3) characteristics of ideal solution. (6 Marks) c) Draw and label phase diagram for water and carbon dioxide. Discuss the differences between both phase diagrams.
