- In Chapters 17 and 18 we have derived expressions for the absolute amounts of the energies H and G. However, in tables of thermodynamic data, we always tabulate H and G that is, changes in enthalpy and Gibbs energy. How do you explain this apparent discrepancy?Derive the generalized Gibbs equations, considering chemical potentials and more than one phase.Define Gibbs energy.

Internal energy Enthalpy Gibbs energy Helmholtz energyThe Gibbs Free Energy, Enthalpy, and Entropy are state functions; hence, path-dependent. True False
- With a typical example, explain the concept of residual entropyDiscuss the relations between: the entropy (particularly of the universe), the standard Gibbs' free energy change, the spontaneity, the equilibrium constant, and the equilibrium position for or associated with a process.7) Use the Maxwell relations to show that the entropy of a perfect gas depends on the volume as Soc R Inv.
