Very interesting section, but it should be integrarted better in the article.
(1) It has several undefined terms.
(2) It should announce somewhere that inhibiting a reaction through mimicking a transition state complex is desirable, either to test theories or prevent reactions (say for medical purposes). As it stands, the idea of inhibition is introduced indirectly, the reader has to be clever to catch it.

Can anyone explain WHY the symbol ‡ is used to denote properties of the transition state? All my textbooks just say that it is so used, but none of them explain the origin and meaning of the symbol. Did it come from Eyring's papers, and did he offer any explanation? Dirac66 ( talk) 21:39, 27 October 2016 (UTC)

TST assumes that even when the reactants and products are not in equilibrium with each other, the activated complexes are in quasi-equilibrium with the reactants. As illustrated in Figure 2, at any instant of time, there are a few activated complexes, and some were reactant molecules in the immediate past, which are designated [ABl]‡ (since they are moving from left to right). The remainder of them were product molecules in the immediate past ([ABr]‡). Since the system is in complete equilibrium, the concentrations of [ABl] ‡ and [ABr]‡ are equal, so that each concentration is equal to one-half of the total concentration of activated complexes:[citation needed]
There are two odd aspects here: the last sentence says "since the system is in complete equilibrium" seems to contradict the first sentence. Second, why would the quantities $[AB_l]^\ddagger$ and $[AB_r]^\ddagger$ be equal, unless the activation energies of both forward and reverse reactions are equal (which would imply that starting material and product are the same energy)? Could someone make sense of this? It also isn't well-explained why these facts are significant.

Also rate equations should be preferably formulated with activities, see https://www.researchgate.net/post/Does-anyone-have-experience-with-the-use-of-activities-instead-of-concentration-in-reaction-rate-equations Biggerj1 ( talk) 23:36, 16 December 2020 (UTC)
