Question

when potassium permanganate is heated 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?
A. The reaction is endothermic
B. The potential energy of the system is constant
C. The reaction is exothermic
D. The activation energy of the system is negative

Answer 1

The correct statement about the reaction where potassium permanganate and glycerol react, resulting in products with lower potential energy than the reactants, is:

**C. The reaction is exothermic.**

In an exothermic reaction, the products have lower energy than the reactants, and this release of energy typically occurs in the form of heat.
