LeChatelier's Principle



Summary
The essence of the content revolves around explaining Le Chatelier's principle and its application in predicting the direction of shift in chemical equilibria in response to various stresses such as changes in reactant/product concentrations, pressure, and temperature.
  • Le Chatelier's principle posits that a chemical system at equilibrium will adjust to counteract any imposed change, aiming to re-establish equilibrium.
  • Adding or removing reactants or products shifts the equilibrium to the side that counterbalances the change, visualized effectively through a seesaw analogy.
  • Changes in pressure and temperature also influence the direction of the shift, depending on the specifics of the reaction, such as the number of moles of gas involved or whether the reaction is endothermic or exothermic.
  • Certain interventions, like adding a catalyst or a noble gas, do not alter the position of equilibrium but may affect the rate of reaction or the total pressure, respectively.
  • Understanding how to apply Le Chatelier's principle allows for the prediction of how a system at equilibrium will respond to various changes, aiding in the manipulation of chemical reactions.
