Which of the following statements is false?
A. The term “gamma-phi” modeling refers to modeling the vapor-liquid equilibrium of a mixture by accounting for the non-idealities from the ideal solution model through an activity coefficient for the liquid and accounting for the non-idealities from an ideal gas through a fugacity coefficient for the vapor.
B. The Poynting correction factor is used to account for the impact of pressure on the activity coefficient.
C. The natural logarithm of the activity coefficient of a component in a mixture is a partial molar property of the excess molar Gibbs free energy of the mixture divided by RT.
D. All of the above are true.
E. All of the above are false.
A. Incorrect. This is true and defines the gamma-phi modeling approach.
B. Correct. The Poynting correction is used to calculate the impact of pressure on the fugacity (relative to its saturation value).
C. Incorrect. This is true and is Equation 11.73.
D. Incorrect. At least one is a false statement.
E. Incorrect. At least one is a true statement.
