The diagram below shows how the potential energy changes during a
chemical reaction. What can you tell about the reaction from the diagram?
Potential Energy
Reaction Progress
A. The reaction is exothermic because it has a low activation energy.
B. The reaction is endothermic because the reactants are higher in
energy than the products.
C. The reaction is endothermic because it has a low activation
energy
D. The reaction is exothermic because the reactants are higher in
energy than the products.

According to the graph given in the image, ''The reaction is exothermic because the reactants are higher in energy than the products.'' Hence the correct answer is Option (D).

What is Exothermic Reaction ?

An exothermic process is one that gives off heat which is transferred to the surroundings.

Therefore, According to the graph given in the image, ''The reaction is exothermic because the reactants are higher in energy than the products.'' Hence the correct answer is Option (D).
