Define chemical equilibrium with examples.
Dear student,
Chemical equilibrium is the condition where the rate of the forward reaction equals the rate of the reverse reaction, such that the concentrations of reactants and products in a chemical reaction taking place in a closed system no longer change with time.
Characteristics of chemical equilibrium are:
1. Equilibrium can be obtained by setting up the reaction from either side.
2. It is dynamic in nature, both forward and backward reactions occur at the same rate.
3. At equilibrium, there is no net change in the concentration of the species of the reaction.
4. The equilibrium state is not affected by the presence of the catalyst.
5. Equilibrium is achieved when the reaction is carried out in a closed container only.
Eg-
2NO(g) + Cl2(g) 2NOCl(g)
This is the example of a reaction in equilibrium where the rate of the forward reaction is equaled to the rate of backward reaction.
