In this lecture, we discuss the extremum principles for various thermodynamic potentials such as Helmholtz free energy, Gibbs free energy, internal energy, and enthalpy. Under different constraints on the system, these potentials attain a minimum at the equilibrium. Thereafter, we introduce the concept of availability and show that it yields a unifying criteria for the equilibrium conditions. (c) Supreet Singh Bahga, IIT Delhi
