Consider a closed vessel initially containing 1 mol of pure tetrahydrofuran at 74"c and 120 kpa imagine that pure chloroform is slowly added at constant temperature and pressure until the vessel contains 1 mol tetrahydrofuran and 9 mol chloroform describe the evolution of phases and phase compositions during this process. comment on the practical feasibility of carrying out such a process. what sort of device would be required? how would the total system volume change during this process? at what composition would the system volume reach its maximum value?
