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, energy is released to the surroundings as the products are formed, and the potential energy of the products is lower than that of the reactants.
**The reaction is exothermic.**
In an exothermic reaction, energy is released to the surroundings as the products are formed, and the potential energy of the products is lower than that of the reactants.
