Le Chatelier's Principle
Le Chatelier's principle states that when a reaction system is subjected to changes in temperature, pressure, or concentration, the position of equilibrium will shift in the direction that counteracts these changes. This principle provides valuable guidance in predicting the direction in which equilibrium shifts under various conditions and helps chemists devise strategies to manipulate the equilibrium position.
Applications of Le Chatelier's Principle:
Examples:
Increased Temperature: In a reaction involving gases A and B, increasing the temperature will shift the equilibrium position towards the side with more A molecules.
Increased Pressure: When you increase the pressure of a gas-solid equilibrium, the equilibrium position shifts towards the side with more gas molecules.
Increased Concentration of Reactants: When the concentration of reactants is increased, the equilibrium position shifts towards the side with lower concentration of reactants
