Now, let's look at the same Exact diagram. But now we're going to work backwards. So we basically want to begin with a diatomic H two molecule, and we want to somehow get to this H two. So we essentially want to break this covalent bond and form two separate H molecules or h atoms. So that means since we go from a lower energy to a higher energy, we have to input energy to go from this guy to this guy. So we input energy to break the bond to form two individual H molecules.
