Chemical Equilibrium: In a chemical reaction the point at which the rate of formation of products is equal to the rate of formation of the reactants is called Equilibrium position.
In a chemical process there are two reactions going. one is the Forward reaction where the reactants form products and the other Backward Reaction where the products form the reactants.
When the rate of both Forward and backward reaction is same, equilibrium is achieved.
