The potential energy of the reactants is greater than the potential energy of the products.
It shows whether the reaction is exothermic or endothermic.
It shows whether the reaction is exothermic or endothermic.
In an exothermic reaction, the potential energy diagram shows a decrease in potential energy as the reactants transform into products. The reactants have higher energy compared to the products, indicating that energy is released during the reaction, often in the form of heat. The diagram typically features a downward slope from the reactants to the products, with an activation energy barrier that must be overcome for the reaction to proceed. Overall, this results in a negative change in enthalpy (ΔH).
An exothermic reaction is identified on a potential energy diagram by observing that the energy of the products is lower than that of the reactants. This is depicted as a downward slope from the reactants to the products, indicating that energy is released during the reaction. The difference in height between the reactants and products represents the amount of energy released (enthalpy change, ΔH) in the process. Additionally, the activation energy is shown as a peak that must be overcome for the reaction to proceed.
If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.

A potential energy diagram of a chemical reaction illustrates the energy changes that occur as reactants are converted into products. It shows the activation energy required for the reaction to proceed and whether the overall process is exothermic or endothermic. The diagram can also reveal the stability of the reactants and products.
The difference in potential energy between the reactants and products.
The potential energy of the products is greater than the potential energy of the reactants.
It shows whether the reaction is exothermic or endothermic.
The potential energy of the products is greater than the potential energy of the reactants.

If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
This shows that the reaction is endothermic because energy is absorbed in the reaction and not produced.
