11. Chemists use reaction coordinate diagrams as both an analytical and pedagogical aid for rationalizing and illustrating thermodynamic events. 12. A reaction coordinate diagram can also be used to qualitatively illustrate kinetic and thermodynamic control in a reaction. 13. The reaction coordinate for inner sphere energy is governed by vibrations and they differ in the oxidized and reduces species. 14. Most of these structures detail metal fluoride analogue complexes which are used to mimic different states along the reaction coordinate . 15. The "'transition state "'of a chemical reaction is a particular configuration along the reaction coordinate . 16. Reaction coordinates are often plotted against potential energy profile ( an intersection of a potential energy surface ) associated to the reaction.17. The latter is drawn, according to Arrhenius and Eyring, as an energy diagram with the reaction coordinate as the abscissa. 18. The S N 2 mechanisms are used as an example to demonstrate how solvent effects can be indicated in reaction coordinate diagrams. 19. Secondly, for a multi-step reaction there may be more than one maximum in the energy vs . reaction coordinate plot. 20. Therefore, the geometric structure of a state can be predicted by comparing its energy to the species neighboring it along the reaction coordinate .
