Title:
What Makes a Chemical Reaction Endothermic or Exothermic?
Description:
Students will analyze the bond energy of the reactants and products in a chemical reaction. Students will develop a model to illustrate how the changes in total bond energy determine whether the reaction is endothermic or exothermic. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
