The reaction in question is exothermic (releases heat) hence its products shall have chemical potential energies lower than that of its reactants- some of the potential energies have been converted to thermal energy during the reaction process.

energy of products is 120 kJ/mol and the activation energy for the forward reaction is 120 kJ/mol. Label the diagram clearly. Is this reaction exothermic or endothermic? Example: Draw an energy level diagram for the reaction described below. (label the axis!) Potential energy of reactants = 350 kJ/mole Activation energy = 100 kJ/mole energy needed for a reaction to happen - this lower activation energy is shown by the dotted red line in the diagram here. Energy level diagrams for endothermic reactions In endothermic reactions the reactants have a less energy than the products . The difference between these two energy levels is the energy absorbed from the surroundings. Endothermic Reaction Energy Level Diagram: Endothermic reactions are depicted in a basic energy level diagram below. The activation energy is the amount of energy that must be delivered to the reactants for them to break through the energy barrier and react. In an endothermic reaction, the result has higher potential energy than the reactants. Potential Energy Diagram Worksheet ANSWERS 1.

In an endothermic reaction, the reactants absorb heat energy from the surroundings to form products. Thus, the products formed have more energy than the reactans, H products > H reactants. Therefore, ΔH is positive. Energy level diagrams are used to shows the energy content of chemicals before and after a reaction. They show:

An endothermic reaction must have a positive change in enthalpy. That is, Delta"H">0. This means that the system absorbs heat. To represent the positive change in enthalpy, the potential energy of the reactants must be LOWER than that of the products. Notice how the end of the "hump" is higher than the beginning, showing how the system gained energy during the course of the reaction.
