10.0 Introduction to Energy Changes: Thermodynamics, Heat vs. Temperature, and Enthalpy

Chapter 10: Energy Changes in Chemical Reactions | Introduction General Chemistry: The Complete College Lecture Series This chapter covers energy and thermodynamics, the first law, heat and work, enthalpy, calorimetry, Hess's law, standard enthalpies of formation, bond enthalpies, and the Born-Haber cycle and lattice energy. This introduction to Chapter 10, Energy Changes in Chemical Reactions, is taught by Dr. Kunapareddy. It previews the next part of the general chemistry course and explains why enthalpy, the change in energy in a chemical reaction, is the main goal of the chapter. The lecture separates thermodynamics from thermochemistry, explains the difference between heat and temperature, and introduces the system and the surroundings. It then surveys kinetic and potential energy, how bond energy stores energy in molecules (why fat holds more energy per gram than carbohydrate or protein), and previews delta H, delta G and the Gibbs free energy equation that connects Chapters 10, 14 and 15. These are comprehensive general chemistry lecture videos, built to help students succeed in the course, with clear step-by-step explanations, closed captions and practice quiz questions.
