Le chateliers principles

• Pressure


  Increased pressure moves the equilibrium position in the direction of fewer molecules
• Moving equilibrium position


  Increases/decreases yield
• Temperature


  One direction is exothermic one direction is endothermic. If temperature increases equilibrium position moves towards the endothermic process
• Stresses that can change the equilibrium position

  • Pressure
  • Concentration
  • Temperature
• Effects of concentration on equilibrium position


  • Increasing concentration of reactant on the left moves equilibrium position to the right
  • Decreasing concentration of reactant on the left moves equilibrium position to the left
• Dynamic equilibrium

  A reversible reaction that happens in a closed container where the rate of the forward and backward reactions are equal
• If a product is removed, the equilibrium position moves in the same direction to make more of that product
• Symbol for reversible reactions
