<P> In chemistry, Le Chatelier's principle (pronounced / lə ˈʃɑːtəlieɪ /), also called Chatelier's principle or "The Equilibrium Law", can be used to predict the effect of a change in conditions on a chemical equilibrium . The principle is named after Henry Louis Le Chatelier and sometimes Karl Ferdinand Braun who discovered it independently . It can be stated as: </P> <Dl> <Dd> When any system at equilibrium is subjected to change in concentration, temperature, volume, or pressure, then the system readjusts itself to counteract (partially) the effect of the applied change and a new equilibrium is established . </Dd> </Dl> <Dd> When any system at equilibrium is subjected to change in concentration, temperature, volume, or pressure, then the system readjusts itself to counteract (partially) the effect of the applied change and a new equilibrium is established . </Dd>

Le chatelier's principle states that equilibrium of a reaction can be affected by a change in
