The correct statement about the reaction between potassium permanganate and glycerol, where the potential energy of the products is less than that of the reactants, is:
**The reaction is exothermic.**
In an exothermic reaction, the energy released when products are formed is greater than the energy required to break the bonds in the reactants, leading to a net decrease in potential energy of the system.
**The reaction is exothermic.**
In an exothermic reaction, the energy released when products are formed is greater than the energy required to break the bonds in the reactants, leading to a net decrease in potential energy of the system.
