Reaction coordinate diagrams energy changes described

In a typical reaction coordinate diagram which describes energy changes as the reactants progress to products, the ordinate is calibrated in energy units and the abscissa (reaction coordinate) describes structural changes that occur on going...

A two-dimensional free energy reaction diagram may be described intuitively for a fundamental reaction (Figure 1). The curve at the saddle point and for most of the reaction coordinate can be modelled by the paraboloid Equation (6) but the equation fails to predict the minima in potential energy at the reactant and product positions. The value of will increase as increases and Equation (6) will have a as negative. The Px or p value for this change is defined as -3pNuy pAa . ... 

As we have already noted, the phenomenological picture of the transition from a = to a = lorO described above is actually based on the assumption that the activation energy changes monotonically although this postulate was initially not formulated. This monotonicity is illustrated by potential diagrams of the type shown in Figure 1.8 where the energy is plotted as a function of a certain reaction coordinate X.
