Chemical Equilibrium: Activity and Equilibrium Constant

This lecture covers the concept of chemical equilibrium, where reactions reach a dynamic balance. It explains the equilibrium constant, activity coefficients, and the relationship between reaction quotient and equilibrium constant. The lecture also discusses how to calculate the equilibrium constant, the effect of temperature and pressure on equilibrium, and the use of catalysts. Additionally, it explores the impact of adding or removing substances on equilibrium, as well as the role of volume and temperature changes. The presentation concludes with a detailed explanation of the Van 't Hoff equation and the quantitative calculation of the equilibrium constant using Gibbs energy.
