2.8. Consider a closed vessel initially containing 1mol of pure ethyl acetate at 70C and 86kPa. Imagine that pure ethanol is slowly added at constant temperature and pressure until the vessel contains 1mol ethyl acetate and 9mol ethanol. 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? Problems 12.9 through 12.14 refer to the Txy diagram for ethanol(1)/ethyl acetate(2) shown in Fig. 12.20.
