Unit 8: Thermodynamics

Learning Objectives for Unit 8 is located here.

You have previously learned about energy and its relationship to chemical processes (enthalpy). We will broaden our attention to other thermodynamic state functions known as entropy, a measure of "randomness," and Gibbs Free Energy, a quantity used to predict spontaneity--where the latter incorporates both enthalpy and entropy. To be discussed: spontaneous processes, entropy and the Second Law of Thermodynamics, Entropy changes in chemical reactions, Gibbs Free Energy, free energy and temperature, and free energy and the equilibrium constant.
