It discusses how adding reactants or products affects equilibrium, maintaining the equilibrium constant despite changes. It elaborates on how changing the concentration, such as adding sodium acetate or a ligand, affects reactions, and also how pressure and volume changes influence equilibrium through the ideal gas law.
