Equilibrium

Unit 7: Equilibrium in AP Chemistry focuses on the dynamic balance of reversible chemical reactions. Key topics include the equilibrium constant (
𝐾
K), reaction quotient (
𝑄
Q), Le Châtelier’s Principle, and the relationship between equilibrium and Gibbs free energy. Students analyze how changes in concentration, pressure, and temperature affect equilibrium systems. This unit also introduces acid-base equilibria and solubility equilibria, providing a comprehensive understanding of chemical systems in balance and their real-world applications.
