2. 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.

3. 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.
