Which of the following statements is false?
A. The ideal solution molar enthalpy is equal to the ideal gas molar enthalpy if evaluated at the same temperature and pressure.
B. The partial molar volume of component i in the ideal gas state at the system temperature and pressure is not equal to the pure component molar volume evaluated at the system temperature and the partial pressure of component i.
C. The partial molar internal energy of component i in the ideal gas state evaluated at the system temperature is equal to the pure component molar internal energy of component i in the ideal gas state evaluated at the system temperature.
D. All of the above.
E. None of the above.
A. Correct. This is a false statement. Molar enthalpy evaluated if the system is modeled as an ideal solution is different than if the system is modeled as an ideal gas – even if the temperature and pressure are the same.
B. Incorrect. This is a true statement.
C. Incorrect. This is a true statement.
D. Incorrect. At least one statement is true.
E. Incorrect. At least one statement is false.
