Equilibrium

• A reversible reaction is when the reactants turn into products and the products turn into reactants.
• Dynamic equilibrium is the point in a reversible reaction when the rate of forward and reverse reactions are the same.
• The three reaction conditions that can be changed are:

  • Concentration.
  • Temperature.
  • Pressure.
• Le Chatelier's Principle is the position of equilibrium will shift to oppose external changes.
• At dynamic equilibrium, increasing the concentration of reactants will favour the forward reaction.
• At dynamic equilibrium, decreasing the concentration of products will favour the forward reaction.
• At dynamic equilibrium, increasing the pressure will favour the reaction that leads to the least molecules.
• At dynamic equilibrium, decreasing the pressure will favour the reaction that leads to the most molecules.
• At dynamic equilibrium, increasing the temperature will favour the endothermic reaction.
• At dynamic equilibrium, decreasing the temperature will favour the exothermic reaction.
