You need to calculate the cross-virial coefficient (B’12) for a mixture. You know that B’1 = - 0.0003 m3/mol, while B’2 = - 0.0006 m3/mol. What is a good estimate of B’12?
A. 0.00045 m3/mol
B. -0.00045 m3/mol
C. -0.000424 m3/mol
D. 0.000424 m3/mol
E. It is not possible to answer this without knowing the composition of the mixture.
A. Incorrect. We do not use arithmetic means for the cross-virial coefficient.
B. Incorrect. We do not use arithmetic means for the cross-virial coefficient.
C. Correct. You have properly selected the negative root from the geometric mean.
D. Incorrect. You have used the right formula (geometric mean), but selected the wrong root.
E. Incorrect. The cross-virial coefficient does not depend on the composition. The mixture virial coefficient (B’m) does, however.
