Chemical Equilibrium: Thermodynamics and Reversibility

This lecture covers the fundamentals of chemical equilibrium, including the relationship between Gibbs energy and equilibrium constant, Le Chatelier's Principle, solution behavior, and the concept of activity in mixtures. It also discusses the impact of changes in conditions on equilibrium and the prediction of reaction evolution based on the reaction quotient. The lecture emphasizes the importance of homogeneous and heterogeneous equilibria, as well as the equilibrium constant's role in determining the direction of a reaction. Practical examples and theoretical principles are combined to provide a comprehensive understanding of chemical equilibrium.
