Le Châtelier’s Principal Le Châtelier’s principle states that: “A system at equilibrium will react to a ‘stress’ in a way that counteracts the ‘stress’.” . A “stress” is a change in an experimental condition such as the temperature, pressure or concen_tration of one of the species. Here’s a brief description of Le Châtelier’s principle. 1. Change in the concentration of a reagent If the concentration of a substance is increased , the equilibrium will shift to decrease the concen_tration of the added substance. Conversely, removing some of a substance will cause a shift which will form more of that substance. The word shift is used to mean that either the forward or the reverse reaction will proceed, thus forming more of the products or reactants, respectively. The position of equilibrium is said to be shifted to the right if the forward reaction pro_ceeds and more product is formed, or to the left if the reverse reaction pro_ceeds to form more reactants. 2.
