Question

Based on the reaction and bond energies listed in the table, would this reaction occur without the addition of energy?

A. No, it would not occur without additional energy because the reaction is endothermic.

B. Yes, it would occur without additional energy because the reaction is endothermic.

C. No, it would not occur without additional energy because the reaction is exothermic.

D. Yes, it would occur without additional energy because the reaction is exothermic.

Answer 1

D. Yes, it would occur without additional energy because the reaction is exothermic. The bond energy of the products (2AB) is greater than the bond energy of the reactants (A2+B2), indicating that energy is released during the reaction. Therefore, the reaction is exothermic and would occur spontaneously without the addition of energy.
