    • Any effect which causes a change in the Brønsted coefficient for the reaction of 4-MeO-1, such as a change in the intrinsic reaction barrier or a change to a concerted reaction mechanism, will be very difficult to detect as curvature that is caused by the change in the position of a single data point on the correlations shown in Figure 6A. This effect will be easier to detect on the correlations shown in Figure 7A, because all of the deviant rate constants are present on the single Brønsted correlation for the reaction of the deviating compound 4-MeO-1.

    • + lies on the correlation between β and reaction driving force determined for protonation of X-1 by carboxylic acids (Figure 6B). This provides evidence that there is not a large difference in the value of intrinsic barrier Λ for the reaction of these different types of Brønsted acids.
