11.43 How much energy in kilojoules is released when 25.0 g of ethanol vapor at 93.0°C is cooled to -11.0°C? Ethanol has mp AHusion J/(K mol) for the liquid and 65.6 J/(K mol) for the vapor. 11.44 Draw a molar heating curve for ethanol, C,H,OH, similar to that shown for water in Figure 11.3. Begin with solid ethanol at its melting point, and raise the temperature to 100 °C. The necessary data are given in Problem 11.43, -114.1 °C, bp = 78.3 °C, AH,ap 4.93 kJ/mol. The molar heat capacity is 112.3 38.56 kJ/mol, and
