Sections

Introduction to Equilibrium

Equilibrium in chemistry refers to the state where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.

1 Section Overview

Start current section content and materials

Key Concepts

This section introduces equilibrium in reversible chemical reactions, highlighting key concepts such as dynamic equilibrium, the equilibrium constant, and Le Chatelier’s Principle.

2 Section Overview

Start current section content and materials

2.1 Reversible Reactions

Reversible reactions describe the state where reactants convert to products and vice-versa, establishing a dynamic equilibrium.

2.2 Dynamic Equilibrium

Dynamic equilibrium characterizes reversible chemical reactions where reactants and products coexist at stable concentrations due to equal reaction rates.

2.3 Equilibrium Constant (K)

The equilibrium constant (K) quantitatively expresses the relationship between reactants and products in a reversible chemical reaction at equilibrium.

2.4 Le Chatelier’s Principle

Le Chatelier’s Principle states that if an equilibrium system is disturbed, it will shift to counteract the change and restore balance.

Factors Affecting Equilibrium

This section discusses the various factors that influence the position of chemical equilibrium, including concentration, temperature, pressure, and catalysts.

3 Section Overview
