Question

When potassium permanganate and glycerol react, the potential energy of the products is less than the potential energy of the reactants. Which statement about this reaction is correct?(1 point) Responses The reaction is endothermic. The reaction is endothermic. The total potential energy of the system is constant. The total potential energy of the system is constant. The activation energy of the system is negative. The activation energy of the system is negative. The reaction is exothermic.

Answer 1

The correct statement about the reaction between potassium permanganate and glycerol is:

**The reaction is exothermic.**

This is because the potential energy of the products is less than that of the reactants, indicating that energy is released during the reaction.
