Equilibrium is a state of balance or stability in a system, where the forces and factors involved are equal and opposite, resulting in no net change or movement.
Equilibrium is achieved when the rates of the forward and reverse reactions are equal, and there is no overall change in the concentrations of reactants and products.
The factors that can affect equilibrium in a system include temperature, pressure, and concentration of reactants and products. Changes in these factors can shift the equilibrium in one direction or the other.
Equilibrium can be disturbed by changes in the factors that affect it, such as temperature, pressure, or concentration. For example, increasing the concentration of reactants can shift the equilibrium towards the products, while decreasing the concentration of products can shift it towards the reactants.
Equilibrium is important in chemical reactions because it determines the extent to which a reaction will proceed. It also allows for reversible reactions, where reactants can be converted into products and vice versa, depending on the conditions.
