Curves
relating log(K), measured at 30˚C, to the number of substituent groups
that correspond to each series given by equations (19), (20) and (21) are shown
in figure 12 and the values for the slopes and intercepts of each curve are
included. It is seen that all the nine points fall on the predicted three
straight lines and the indices of determination are 0.995, 0.999 and
0.995 respectively). Equations (19) and (21) should have the same slopes
equivalent to (
) but different intercepts.
