Question

Calculate the values of delta U, delta H, and delta S for thefollowing process: 1 mole of liquid water at 25 degrees Celsius and 1atm   ---->  1 mole of steam at 100 degreesCelsius and 1 atm. The molar heat of vaporization of water at 373 K is 40.79 kJ /mol, and the molar heat capacity of water is 75.3 J /K.mol.  Assume the molar heat capacity to be temperatureindependent and ideal gas behavior. Calculate the values of delta U, delta H, and delta S for thefollowing process: 1 mole of liquid water at 25 degrees Celsius and 1atm   ---->  1 mole of steam at 100 degreesCelsius and 1 atm. The molar heat of vaporization of water at 373 K is 40.79 kJ /mol, and the molar heat capacity of water is 75.3 J /K.mol.  Assume the molar heat capacity to be temperatureindependent and ideal gas behavior.

Explanation / Answer

delta U =delta H as it is liquid

75*1*75.3J +40.79*1000 = 46437.5 J

deltaS =dQ/T = 40.79*1000/373 =109.35 J/K
