What is Chemical Equilibrium?
In Chemistry, Chemical Equilibrium is defined as a condition in which the concentration of reactant and product becomes equal and does not change with time. In this state, the rate of the forward reaction becomes equal to the rate of the reverse reaction and there is no net change in the amount of substance involved. It is a reversible chemical reaction in which the products when formed react again to produce the original reactants.
Definition of Chemical Equilibrium
The state of chemical equilibrium is defined as a condition where there is no further change in the concentration of the reactants and the products and the system attains a state of equilibrium.
When a state of chemical equilibrium is achieved, the continuous interchanging of molecules between the reactants and the products becomes equal, due to which the rate of forward and backward reactions becomes equal, and such a state is known as a state of dynamic equilibrium.
For any reaction in chemical equilibrium, we can break it in two reactions as,
H2(g) + I2(g) ⇌ 2HI(g)
- Forward Reaction H2(g) + I2(g) → 2HI(g)
- Reverse Reaction 2HI(g) → H2(g) + I2(g)

Chemical Equilibrium
Chemical Equilibrium is a condition of a reversible chemical reaction, where the rate of forward and backward reactions are equal. In Chemical equilibrium, the concentrations of the products and reactants remain constant i.e. it does not change with time. This is a state after which there are no observable changes in the properties and the system becomes constant. In this state, the forward reaction proceeds at the same rate as the reverse reaction.
In this article, we will learn more about chemical equilibrium, its types, its examples, and more, so Let’s get started.
