Consider a closed vessel initially containing 1 mol of pure ethyl acetate at 70°C and 86 kPa. Imagine that pure ethanol is slowly added at constant temperature and pressure until the vessel contains 1 mol ethyl acetate and 9 mol ethanol. Describe the evolution of phases and phase compositions during this process. Comment on the practical feasibility of carrying out such 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 volume?

A 8.7 kg of lead initially at 210∘C is dropped into an insulated basin containing 21.9 kg of water initially at 27.1∘C. Assume that he water does not undergo any phase change when the hot metal was initially dropped into the water. Assuming no heat losses from the container, what is the final equilibrium temperature between the water and the lead?

Draw the general shape of the temperature-energy graph for ethanol from: -200C to 100C. The melting and boiling points of carbon ethanol are -114.1C and 78.37C, respectively. Label the diagram in terms of the phases present at each line of the graph.
