Question

this diagram shows the amount of energy stored in the reactants and products of an exothermic chemical reaction. because energy was released, the products have less stored energy than the reactants. which of these diagrams shows the energy change in an endothermic reaction?

Explanation:

In an endothermic reaction, energy is absorbed. This means the products have more stored energy than the reactants. Looking at the diagrams:

• Diagram A shows a decrease in energy (exothermic).
• Diagram B shows no change in energy.
• Diagram C shows an increase in energy (endothermic as products have more energy than reactants).
• Diagram D shows a decrease in energy (exothermic).

Answer:

C
