Endothermic Vs. Exothermic Reaction Graphs

Endothermic Vs. Exothermic Reaction Graphs Endothermic Reaction: a reaction in which the products have more stored energy than the reactants. The reaction ABSORBS energy from the surrounding environment and the products use up this energy to create chemical bonds. The products are colder than the reactants.

Endothermic Vs. Exothermic Reaction Graphs Exothermic Reaction: a reaction in which the products have less stored energy than the reactants. The reaction RELEASES energy when bonds are broken. The products are hotter than the reactants.

Exothermic Reaction Graph Activation Energy-the energy needed to start a reaction Energy stored in the Reactants E N R G Y Energy released in the reaction Energy Stored in the Products TIME

Endothermic Reaction Graph Activation Energy-the energy needed to start a reaction Energy Stored in the Products Energy stored in the Reactants E N R G Y Energy absorbed in the reaction TIME
