Chemical Equilibrium
Learning Time: 5-15 hours
Content: Chemical equilibrium is a subject that examines the situation in which the forward and reverse reactions in closed systems are equal. This area covers the equilibrium constant (K), Le Chatelier’s principle, equilibrium shift, acid-base equilibrium, heterogeneous equilibria, and practical applications. TYT focuses on basic equilibrium concepts, while AYT focuses on equilibrium calculations and industrial processes. In the current 2025 curriculum, it is also addressed in the context of environmental chemistry and sustainability. Learning this topic forms the basis for the control of chemical systems.
