A gas obeys the equation of state (for 1 mole): P(V-b) = RT where b amounts to 0.5% of the total volume at 27°c and 1 bar. Its molar heat capacity. measured at a pressure of 1 bar is given by Cp(J/mol/K) =29.3+0.0126T(K) What are the changes in molar entropy and molar enthalpy when it is heated from 27°c to 227°c at 1 bar? what are the changes in molar entropy, molar enthalpy and molar Gibbs free energy on compression from 1 bar to 100bar at 227°c?​
