Unformatted text preview: py of H2O at 100. C and 1 atm (ΔvapH = 40.7 kJ/mol), calculate the change in entropy for a system composed of 1.50 mol of water as a result of the irreversible o (very fast) decrease in temperature from the initial state characterized by 1.50 mol H2O(g) at 150. C and o 1.00 atm to a final state characterized by 1.50 mol H2O(l) at 50. C and 1.00 atm. The relevant constant o o pressure molar heat capacities are CPm (H2O(l)) = 75.3 J/K.mol and CPm (H2O(g)) = 33.6 J/K.mol. 3 Question 10: (10 points) 0.3177 g phenol (C6H5OH(s)) is placed in an adiabatic constant volume bomb calorimeter of heat capacity, o - 1 CCAL = 8.80 kJ. C (this heat capacity accounts for both the calorimeter parts and the water in which the bomb is placed). Combustion of phenol with an excess oxyge...
