Step 1
Which statement is correct for an endothermic reaction?
Answer
In an endothermic reaction, the bonds in the products require more energy to break than the energy released from breaking the bonds in the reactants. This implies that as the temperature decreases, more energy is needed to break the bonds in the reactants compared to the products. Therefore, the correct option is D: "decreases" where more energy is needed to break bonds in reactants than is needed to make bonds in products.
