Explain factors affecting equilibria.

Explanation

Factors affecting equilibrium are:
A chemical reaction at equilibrium will maintain its equilibrium concentrations indefinitely unless it is disturbed. Such disturbances (also called constraints or stresses) include a change in temperature, a change in concentration of a reactant or product, and a change in pressure within the reacting mixture. The effect of temperature and pressure on the position of equilibrium of a reversible reaction can be calculated quantitatively.
However, the effect of concentration, temperature and pressure can be predicted qualitatively with the help of a generalisation proposed by Le-Chatelier, a French chemist in 1884. This principle is based fundametanlly on the second law of thermodynamics.
