Le Chatelier Principle Worksheet. Le Chatelier's principle implies that a pressure increase shifts an equilibrium to the side of the reaction with the fewer number of moles of gas, while a pressure decrease shifts an equilibrium to the side of the reaction with the greater number of moles of gas. When a reversible reaction is at equilibrium disturbances (in concentration, temperature, pressure, etc.) will be offset.
Le Chatelier's principle is an observation about chemical equilibria of reactions. Le Chatelier's Principle states that when a system at equilibrium is subjected to a stress, the system will shift its equilibrium point in order to relive the stress. In other words, it can be used to predict the direction of a chemical reaction in response to a change in conditions of temperature, concentration, volume, or pressure.
