A liquid mixture containing 25mol% benzene and 75mol% ethyl alcohol, in which components are miscible in all proportions, is heated at a constant pressure of 1atm ( 101.3kPa,760 ton) from a temperature of 60C to 90C. Using the following Txy experimental data, perform calculations to determine the answers A - If 100 moles of the feed is heated to 72C, find the amount of liquid and vapor phases created. Find the composition of the residual liquid and the vapor phase. B - If 100 moles of the feed is heated in a way that vapor phase has a composition of 0.36 mole fraction of benzene; find the temperature of the mixture, amount of vapor phase and the composition of the residual liquid. C - if the liquid obtained in part (A) is further heated to evaporate 50% of the total amount, what will be the composition of new vapor phase
