Refer to the attached Pxy diagram for vapor / liquid equilibrium for chloroform ( 1 ) / tetrahydrofuran ( 2 ) at 5 0 C

Refer to the attached Pxy diagram for vapor/liquid equilibrium for chloroform(1)/tetrahydrofuran(2) at 50C. Respond to the following questions with a few short sentences and some simple calculations. Feel free to draw on the graph to prove your answer.
(a) On the plot, identify which line is the bubble line and which line is the dew line.
(b) The pressure of a mixture of chloroform and tetrahydrofuran at 50C is measured to be 62kPa. What are the possible compositions of the liquid and vapor phases?
(c) Consider a mixture with x1=0.80, initially at 50C and 70kPa. Describe the evolution of phases and phase compositions as the pressure is gradually red to 50kPa.
(d) What is the composition of the azeotrope for the system?
(e) Consider a closed vessel initially containing 1mol of tetrahydrofuran at 52kPa. Imagine that pure chloroform is slowly added at constant tem and pressure until the vessel contains 1mol tetrahydrofuran and 9m chloroform. Describe the evolution of phases and phase compositi this process. Comment on the practical feasibility of carrying outs What sort of device would be required?
