See the diagram, which resembles figure 29–10.
The activation energy, 1.3 eV, is the energy needed to lift the atoms of the system, initially separated by very large r, over the potential energy barrier.
The dissociation energy, 1.6 eV, is the energy released when the bond is broken and the molecule is disassociated. It is the difference in energy when the two atoms are separated by the equilibrium bond length, compared to the energy when the atoms are separated by very large r.
