Endothermic and Exothermic Reactions

Guided Notes

3 key concepts

  • 1

    In an exothermic reaction, heat is released from the reaction, while in an endothermic reaction, heat is absorbed.

  • 2

    In an exothermic reaction, the reactants have more energy than the products, resulting in a downhill energy diagram.

  • 3

    Activation energy is the energy required to initiate a reaction by pressuring the bonds of the reactants.
