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 reaction 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.
