Question

Why the reaction is endothermic in the figure shown below?

• A. Because product is at higher energy than reactant
• B. Because product is at lower energy than reactant
• C. Because product is at same energy as reactant
• D. None of the these

Answer 1

Answer: (A)

The explanation for the correct option:

Option(D) Because the product is at higher energy than the reactant

• The product at higher energy than the reactant.

• Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.

• These reactions lower the temperature of their surrounding area, thereby creating a cooling effect.

• The potential energy of the product in an endothermic reaction is higher than that of the reactants. This gap in the potential energy accounts for the energy that was absorbed by the system during the chemical reaction.

Hence, Option(D) Because the product is at higher energy than the reactant is shown in the energy level diagram of the endothermic reaction
