Question

This problem involves the same compound that was examined in Problems 6-14 through 6-17, which in the vapor phase was described by the EOS:

with a = 0.3 × 10−16 m3/mol Pa2 K.
This compound has vapor pressures of Psat = 5 50 kPa at T = 323 K and P = 500 kPa at T = 373 K. Saturated liquid at both T = 323 K and T = 373 K has V ≈ 1.25 × 10−4 m3/mol. Estimate each of the following.
A. The fugacity in the vapor phase at T = 323 K and P = 10 kPa.
B. The fugacity in the liquid phase at T =323 K and P = 10 MPa.
C. The fugacity in the vapor phase at T = 373 K and P = 300 kPa.
D. The fugacity in the liquid phase at T = 373 K and P = 10 MPa.
