[26 marks) b) The figure shown below is for benzene and toluene system at 1 atm. From the figure determine the followings: i) Label the diagram [1 mark] ii) Show from figure, if the mixture has 40mol% benzene, then at what temperature the mixture will boil and what will be the first vapor composition? [4 marks] iii) Show from figure, will the same mixture boils at 85 C? [2 mark] Show from figure and estimate the compositions if the same system is brought to a condition of pressure of 1 atm and temperature of 100 C.
