Consider the condensationof 0.50 mol of ethanol vapor at 38.3oC and 1bar.
Calculate the heat, theentropy change for the system, the entropy change forthe surroundings and the total entropy change forthe universe. What does the sign of DRSo Universe tell you?
The boiling point ofethanol under a pressure of 1 bar is 78.3oC and at this temperatureDvapHo = 39.3kJ.mol%u20101. Thestandard molar heat capacities at constant pressure for ethanolliquid and vapor are 111.46 and 65.44 J/K.mol,respectively.
