What illustrates the changes in a reaction when the catalyst reduces the amount of energy required?

A catalyst lowers the activation energy of a reaction, making it easier for reactants to convert into products. This is illustrated by a potential energy diagram, where the energy barrier for the reaction is reduced in the presence of a catalyst. As a result, the reaction can proceed more quickly and at lower temperatures, without being consumed in the process. Ultimately, this facilitates faster reaction rates while maintaining the same overall energy change for the reaction.
