If you are familiar with chemistry, this quantification of " positional stability " is exactly analogous to the Reaction coordinate diagram used in chemical kinetics and thermodynamics.

In terms of the graph of reaction coordinate versus energy, this is shown by the fact that the tertiary transition state is further to the left than the other transition states.

Secondly, by contrast with TST, the probability of transition is not equal to unity during the reaction and treated as a function of internal energy associated with the reaction coordinate.
36.
The activated complex of a reaction can refer to either the transition state or to other states along the reaction coordinate between reactants and products, especially those close to the transition state . u

This can be visualized in terms of a reaction coordinate, where the transition state is the molecular configuration at the peak of the diagram while the activated complex can refer to any point near the maximum.
39.
The enantioselectivity of CLAs derives from their ability to perturb the free energy barrier along the reaction coordinate pathway that leads to either the " R "-or " S "-enantiomer.
40.
The Evans-Polanyi model assumes the pre-exponential factor of the Arrhenius equation and the position of the transition state along the reaction coordinate are the same for all reactions belonging to a particular reaction family.
