Potential Energy Diagrams for Chemical Reactions, Lecture notes of Physics

Western New Mexico University (WNMU)Physics

Instructions on how to create and interpret potential energy diagrams for chemical reactions. It includes examples of endothermic and exothermic reactions, as well as diagrams for the decomposition of hydrogen peroxide and an example reaction. The document also covers the concepts of activation energy and δh (total energy change), and the effect of catalysts on potential energy diagrams.

What you will learn

What is the activation energy of a forward reaction, and how does it affect the reaction pathway?
What is the potential energy of the products in a given chemical reaction?
What is the potential energy of the reactants in a given chemical reaction?
