The statement that best explains the observation that the chemical potential energy of bond A is greater than the chemical potential energy of bond B is:
The atoms in bond A are held more tightly together than the atoms in bond B.
This is because greater chemical potential energy typically indicates that the bond is less stable (or "weaker") and can release energy upon breaking. If bond A has a higher chemical potential energy, it suggests that the atoms are not held as tightly together compared to those in bond B, which has lower potential energy and thus represents a more stable (stronger) bond.
