Energy Level Diagrams
We can draw energy level diagrams to show energy changes in a reaction. These diagrams show the relative amounts of energy stored in the products and reactants of a reaction, measured in kJ/mol.

Energy Level Diagram - Exothermic (http://gcserevision101.files.wordpress.com/2009/02/energy-level-diagram-exothermic.jpg?w=300&h=221)This is the energy level diagram for an exothermic reaction. The products are at a lower energy level than the reactants, so energy has been released as the reactants form the products. In this release of energy,temperature of the surroundings increases
