Chemical Engineering > GATE 2015 > Residual Properties
Given that molar residual Gibbs free energy, gR, and molar residual volume, vR, are related as (∂gR/∂P)T = vR, find gR at T = 27°C and P = 0.2 MPa. The gas may be assumed to follow the virial equation of state, z = 1 + BP/RT, where B = -10-4 m³/mol at the given conditions (R = 8.314 J/mol·K). The value of gR in J/mol is:
Correct : d
