Placing a stress on any equilibrium system, whether it is chemical, biological, societal, environmental, or personal, causes the equilibrium position to change. Le Chatelier’s Principle allows us to predict the results that follow from changing the conditions of a system at chemical equilibrium . This allows scientists to develop, Le Chatelier’s Principle allows us to predict the results that follow from changing the conditions of a system at chemical equilibrium. This allows scientists to develop techniques to control chemical reactions in natural and industrial settings in order to obtain desired products.
Equilibrium and Le Chatelier’s Principle CHEM 116 POGIL Discussion Fall 2010 UMass Boston 2 MODEL 1: The ICE Table A worked example: Initially 1.50 moles of N2(g) and 3.50 moles of H2(g) were added to a 1 L container at 700 °C. As a result of the reaction CHEMICAL EQUILIBRIUM (ICE METHOD), Le Chatelier’s Principle allows us to predict the results that follow from “stressing,” or in other words, changing the conditions of a system at chemical equilibrium . This allows scientists to develop techniques to control chemical reactions in natural and industrial settings.
EQUILIBRIUM and LE CHATELIER ‘S PRINCIPLE Why? When opposing forces or issues are balanced, a system is said to be in equilibrium . Equilibrium in chemical reactions is dynamic because the forward and reverse reactions are occurring continuously and simultaneously at the same rates.
