Chemical Equilibrium and Its Types
1. Introduction to Chemical Equilibrium
In many chemical reactions, the reaction does not go to completion. Instead, it reaches a state
where:
Reactants are still present
Products are also present
No further visible change occurs
This state is called chemical equilibrium.
2. Definition
Chemical equilibrium is a state in which the rate of forward reaction equals the rate of
reverse reaction, and the concentrations of reactants and products remain constant.
3. Characteristics of Chemical Equilibrium
It is dynamic, not static
Forward and reverse reactions continue
Concentrations remain constant (not necessarily equal)
Achieved in a closed system
Can be reached from either direction
4. Dynamic Nature of Equilibrium
Even at equilibrium:
Forward reaction → forming products
Reverse reaction → forming reactants
👉 Both occur at equal rates
5. Types of Chemical Equilibrium
1. Homogeneous Equilibrium
