And so we begin to form that bond. So we have a partially formed bond here and a partially broken bond here. And because the electron densities aren't overlapping very well, that will increase the energy of the transition state. In fact, according to the diagram, the energy of the transition state represents the highest possible free energy value on the following curve. And so if we are to actually mark down on the curve where that transition state actually is this highest, most peak on the curve, the apex represents that transition state. So we can basically write that this is in fact that transition state.
