Which of the following statements is true?
A. Partial molar properties are functions of temperature, pressure and composition.
B. The partial molar enthalpy of a component in a mixture will not change as the mole fraction of the components in the mixture changes.
C. The SI units of partial molar internal energy are J/K
D. For an ideal solution, the partial molar Gibbs free energy is equal to the pure component Gibbs free energy at the mixture temperature and pressure.
E. None of the above are true.
A. Correct. Equation 9.28 shows this through the definition of partial molar properties.
B. Incorrect. Partial molar properties are functions of temperature, pressure and mole fraction.
C. Incorrect. Partial molar properties have the same units as pure component molar properties. In this case, partial molar internal energy has SI units of J/mol.
D. Incorrect. Remember Gibbs free energy and entropy have additional mixing properties to account for molecular mixing.
E. Incorrect. One statement is a true fact.
