Correctly draw and label the two graphs:

. Use these labels: Energy Time Exothermic Reaction Endothermic Reaction Needs heat from the environment Releases heat into the environment Amount of heat energy needed from the environment Amount of heat energy released into the environment (Use Twice) Reactants Products Activation energy Energy in the reactants Energy in the products Amount of energy needed to start the reaction

Answer: Look at the graphs and make a generalization about the activation energy and energy in exothermic and endothermic reactions.
