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?

A. the activation energy of the system is negative
B. the reaction is endothermic
C. the total potential energy of the system is constant
D. the reaction is exothermic

1 answer

D. the reaction is exothermic

This is because when the potential energy of the products is less than the potential energy of the reactants, it indicates that energy is being released during the reaction, making it exothermic.
