You are designing a process in which toluene is used as a solvent. In order to size process equipment, you need to know the properties at several conditions. Use the Peng Robinson equation to estimate the following quantites.

A. The molar volume at the critical point.

B. The molar volume in the liquid phase at T = 300 K and P = 1 bar.

C. The molar volume in the vapor phase at T = 500 K and P = 10 bar.

D. The change in molar enthalpy when toluene is converted from T = 300 K and P = 1 bar to T = 500 K and P = 10 bar.
