Please give the definition of Le Chatilier's principle. Use this to explain what would happen if you increased the temperature of an equilibrium in which the forwards reaction is exothermic.
Le Chatilier's principle states that, if a change is made to a system at equilibrium, the position of equilibrium will shift to oppose that change. If you increase the temperature of a system where the forwards reaction is exothermic, the position of equilibrium will shift to the left hand side towards products. In doing so, the temperature is lowered to oppose the increase in temperature.
