In specifying the molar Gibbs free energy of a compound, the liquid phase at T = 300 K and P = 1 bar is being used as the reference state. Therefore G^L = 0 at T = 300 K and P = 1 bar. It has been estimated that for pure vapor at T = 300 K and P = 1 bar, G^V = 5.0 × 10³ bar ⋅ cm³/mol. The molar volume of the liquid at the reference state is V^L = 125 cm³/mol.

A. Estimate the liquid phase G at T = 300 K and P = 0.01 bar, relative to this reference state.

B. Estimate the vapor phase G at T = 300 K and P = 0.01 bar, relative to this reference state.

C. Estimate the vapor pressure at T = 300 K.
