II. Thermo-chemistry 1. Introduction. In chapter I. Thermo-Physics, the basic concepts of heat, work, and internal energy were explained along with their relationship to each other. Basic reversible processes, applied to an ideal gas were also examined in some detail. The state variable entropy was defined, and the state functions of Enthalpy, Helmholtz energy, and Gibbs energy were derived. Since virtually all of the above concepts are unfamiliar to most individuals, general discussion with the intent of answering questions of “meaning” and “usefulness” was provided. In chapter II. Thermo-Chemistry, we turn our attentions to some areas of chemistry for which the concepts discussed in I. Thermo-Physics become useful. Questions such as: 1) What heat is evolved in a reaction?, 2) Will this reaction proceed spontaneously?, 3) Has this system reached chemical equilibrium?, will be answered.
