Chapter Overview
Equilibria is the sixth chapter of Class 9 Chemistry. It covers the concepts of chemical equilibrium in reversible reactions. Students learn the distinction between irreversible reactions (going to completion) and reversible reactions (proceeding in both directions).
The chapter details dynamic equilibrium, a state where the forward reaction rate equals the reverse reaction rate, making macroscopic changes appear stopped while microscopic activity continues.
Furthermore, the chapter explains how changing physical conditions affects a chemical reaction at equilibrium. It outlines the effects of temperature changes on exothermic and endothermic equilibria, the impact of pressure variations on gas systems, and the role of catalysts in accelerating the approach to equilibrium without altering its position.
