 Although we have obtained a powerful index of reactivity we remain uncertain of the factors that determine that reactivity. So, let us turn to energy partitioning and divide activation energies into their main parts: energies of former reagents,  //E<sup>R</sup>// and //E<sup>M</sup>//, and interaction energies, //E<sup>int</sup>//. Figure 2 shows the results of such partitioning. The whole situation seems to be complicated enough, each of those parts being greater in absolute value than the resulting activation energy, and no clear correlations are visible.  Although we have obtained a powerful index of reactivity we remain uncertain of the factors that determine that reactivity.

 Moreover, intermolecular interaction energy values are antibate to activation energies, so they cannot be the main and the only factor of reactivity. Moreover, intermolecular interaction energy values are antibate to activation energies, so they cannot be the main and the only factor of reactivity.
