Answer
Equilibrium is a state of balance between two opposing processes/driving forces resulting in no observable changes in the system as time goes by. Chemical equilibrium occurs when the rate of forward reaction is equal to the rate of backward reaction; as a result, the concentrations of products and reactants remain constant.
Examples of dynamic equilibrium are:
1. Melting of ice at $0^{\circ}:$ The rate of freezing is equal to the rate of melting.
2. Sugar powder suspended in water at solubility: The rate of dissolution is equal to the rate of cystallisation.
