Which explains why an activated complex is a high-energy species? activated complexes form during endothermic reactions. activated complexes require new bonds to be made. activated complexes are stable species with strong covalent bonds. activated complexes cannot be formed in the reverse reaction direction?

I think the correct answer is the second option. An activated complex is a high-energy species because activated complexes require new bonds to be made. Activated complexes are unstable arrangement of the atoms that happens rapidly at the peak of the energy barrier. So, they would normally have high kinetic energies.

Answer:

Activated complexes require new bonds to be made.

Explanation:

The activated complex is the state that occurs during a chemical reaction and represents the intermediate state when the reaction reagents are reacting and transforming into products. That is, the activated complex is the middle ground between reagent and product. At this point the activated complex has weakened connections, but it needs new connections to be formed immediately. All of this occurs through a great expenditure of energy.

Accordingly, we can say that what explains why an activated complex is a kind of high energy is what activated complexes require that new connections be made.
