Chapter 18 Entropy, Free Energy, and Equilibrium This chapter covers the concepts of entropy and free energy as part of thermodynamics and relates these concepts to equilibrium. Upon completion of this chapter, your students should be able to: 1. State the three laws of thermodynamics. 2. Provide several examples of spontaneous processes. 3. Give several examples of endothermic spontaneous processes. 4. Define entropy using the terms disorder or randomness. 5. Justify why entropy of one mole of steam is greater than the entropy of one mole of water. 6. Predict the sign on the change in entropy (∆S) for common processes. 7. Describe what is meant by ∆S universe , ∆S system , and ∆S surroundings . 8. Relate ∆S universe for spontaneous processes and for processes at equilibrium. 9. Use thermodynamic table to determine ∆S reaction . 10. Mathematically relate ∆S surroundings to ∆H system and the temperature. 11. Express Gibbs free energy in terms of H, T and S. 12. Predict if a reaction is spontaneous, spontaneous in the reverse direction or at equilibrium from the sign on ∆G. 13. Use thermodynamic tables to determine ∆G of a reaction. 14. Predict the direction of a spontaneous reaction given ∆H, ∆S and T. 15. Calculate ∆S for phase changes given ∆H fusion or ∆H vaporization and the melting and boiling point temperatures. 16. Mathematically describe ∆G in terms of ∆G°, the gas constant, temperature and the reaction quotient. 17. Relate ∆G°, and K, equilibrium constant. 18. Calculate K, equilibrium constant, using data from thermodynamic tables.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
