Problem 10.14: The table below gives data for the system hydrogen sulfide (1) in benzene (2) at 150 °C, using Peng-Robinson equation with k12 = 0.015.

a) Do you expect this system to exhibit a critical point at 150 °C?

b) Determine whether the solution behavior of benzene may be considered ideal in the concentration range x1 = 0 to 0.30.

c) Explain why the fugacity coefficients of H2 S in the liquid and in the vapor are equal at 5.76 bar but different at 36.99 bar.
