Chemical Equilibria and Reactivity

This lecture covers the fundamental concepts of chemical equilibria and reactivity, focusing on gas properties, pressure, gas laws, ideal gases, real gases, and the energy involved in chemical reactions. It explains the relationships between pressure, volume, temperature, and the number of particles in a gas, as well as the laws governing gas behavior. The instructor discusses the ideal gas law, Avogadro's hypothesis, and the general gas law, emphasizing the deviations of real gases from ideal behavior. Additionally, the lecture explores the Joule-Thomson effect, partial pressures, and the energy changes associated with chemical reactions. The importance of energy internal to chemical systems and its relationship to kinetic and potential energy are also addressed.
