ABSTRACT
We need the state function entropy in order to proceed. Roughly speaking, entropy is a
measure of the degree of disorder and the second law of thermodynamics states that the
total entropy increases for all natural processes, and it reaches its maximum when we have
equilibrium. With this as a starting point, we give in this chapter, among other things, the
theoretical basis for use of equilibrium constants. Most of the basic material on entropy is
collected in Appendix B, which should be read before you start this chapter.
