Example 3 Which way will the equilibrium shift if the system temperature goes up heat is added 2 SO2 02 2 SO3 heat Solution Even though heat is not a chemical substance for the purposes of LeChatelier s Principle you can treat it as if it has physical existence Since heat is added the reaction will shift to try and use up some of the added heat In order to do this the reaction must shift to the left Note that since heat is not part of the equilibrium expression the value of Keq would change when the chemical system is heated or cooled
