The following are some examples:
|Reaction coordinate depicting the initial state of the reactants on going to the final state of the products through two different pathways, indicating that state variables are path-independent. ||A typical drug-receptor reaction coordinate as are used on drug-receptor thermodynamics, showing the activated complex.||An SN-2 reaction coordinate, showing the intermediate transition state.|
|A generic reaction coordinate, showing that reaction can be spontaneous in both directions (meaning it can just as easily unravel as did it form), and the red area indicating a region of negative free energy change.|
