Endothermic Potential Energy Diagram
Endothermic Potential Energy Diagram. To represent the positive change in enthalpy, the potential energy of the reactants must be LOWER than that of the products. Endothermic Potential Energy Diagram. • A potential energy diagram shows the change in energy during a reaction. • Heat of Reaction, ΔH: the overall difference in potential energy between the products and the reactants. Δh = pep - per.
The activation energy is the energy that must be provided to the reactants so that they can overcome the energy barrier and react.
To represent the positive change in enthalpy, the potential energy of the reactants must be LOWER than that of the products.
Energy profiles or energy diagrams for endothermic and exothermic reactions with or without a catalyst tutorial with worked examples for Chemistry Energy Profiles (Energy Diagrams) Chemistry Tutorial. An endothermic reaction occurs when energy is absorbed from the surroundings in the form of heat. Bond breaking is endothermic (heat energy is absorbed).
