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. It represents the highest, the maximum energy value in that particular chemical reaction. And this Daggert symbol describes the energy state. So to calculate the free energy value of the transition stage, of that molecule, of that chemical reaction, we simply take this Y coordinate value and we subtract the energy of the reactants.
