Answer the following statement(s) true (T) or false (F)
A. Combining rules describe how the pure component parameters “combine” to make a cross-parameter (such as the a12 parameter for the VDW equation of state).
B. Mixing rules describe how the pure component parameters “mix” to make a cross-parameter (such as the a12 parameter for the VDW equation of state).
C. The k12 parameter is normally reserved for correcting b12 in order to match experimental data.
D. None of the above are true.
E. All of the above are true.
A. Correct. Combining rules are used to determine the cross-parameters for equations of state.
B. Incorrect. Mixing rules are defined differently. Please review the definition in Chapter 12.
C. Incorrect. The k12 parameter normally modifies a12, not b12.
D. Incorrect. At least one of the statements is true.
E. Incorrect. All of the statements are not true – at least one is false.
