Le Chatelier’s Principle Le Chatelier’s Principle is a law in chemistry that is used to predict the changes a chemical equilibrium would go through in response to different stresses applied to that equilibrium. French Chemist Henry Le Chatelier suggested this concept in 1884. He described equilibrium systems as tending to compensate for the effects of perturbing influences. The principle can apply to changes in concentration, changes in temperature, changes in volume, and changes in partial pressure. It describes a chemical equilibrium as shifting to accommodate these changes when they are applied to a chemical equilibrium. This principle is used in chemistry to manipulate the outcomes of reversible reactions, whether it is to increase the products or to increase the reactants. In response to

Unformatted text preview: temperature, Le Chatelier’s principle dictates that added heat to a chemical equilibrium will shift the equilibrium away from the side that produces heat. In other words, it will accommodate the added heat by producing less heat. In a change of substance (i.e. adding more of a product or more of a reactant), the principle dictates that the equilibrium will shift away from the side that the added substance is on. That is to say that the equilibrium will shift to accommodate the additional substance by creating less of that. When pressure is changed, the equilibrium also shifts. An increase in pressure would cause the reaction to shift to the side with fewer moles of gas....
