Which statement is true regarding the energies of the bonds that break and form during a highly endothermic reaction?

The energy needed to break the required bonds is less than the energy released when the new bonds form.

The energy needed to break the required bonds is about the same as the energy released when the new bonds form.

The energy released when the required bonds break is less than the energy absorbed when the new bonds form.

The energy released when the required bonds break is greater than the energy absorbed when the new bonds form.

The energy needed to break the required bonds is greater than the energy released when the new bonds form.

Solutions

Expert Solution

When bonds are broken, energy is absorbed to facilitate the required bond energy for the cleavage of the bond. On the other hand, bond formation resulting into the product molecules furnishes energy (releases energy). A reaction is endothermic when energy is absorbed by the components overall. This happens when the energy needed to break the required bonds is greater than the energy released by the formation of new bonds. Hence, in light of these arguments, Option E (last one) listed above is the correct one.
