Answer: Equilibrium can be defined as the state of an object in which two or more counter-influences, whether internal, external, or a combination of both, act on the body, nullifying each other to keep the object in the same state as it was. The word equilibrium originates in the Latin word libra, which means weight or balance.
Few Examples:
- A book kept on a table at rest
- A car moving with a constant velocity
Equilibrium In Chemical Reaction
Whenever any chemical reaction occurs, there is a change in the number of reactants as reactants keep on decreasing, and as a result, products are formed, and the number of products increases. After a particular time, depending on the reaction, there will not be any change in the reactants and products. This state is the state of Equilibrium.
