If a chemical reaction does not reach its activation energy, which will most likely occur?

Question

The chemical bonds will remain unchanged.
The chemical bonds will break.
The chemical bonds will have high kinetic energy.
The chemical bonds will already be broken.

Answer 1

If a chemical reaction does not reach its activation energy, the most likely occurrence is that the chemical bonds will remain unchanged.

Activation energy is the minimum energy required for a reaction to occur; if this energy is not reached, the reactants will not have enough energy to overcome the energy barrier needed for the reaction to proceed, resulting in no change to the chemical bonds involved.
