Rate coefficients and parameters for inhibition

The general inhibition scheme shown above has been partly dissected to give absolute rate coefficients and parameters for individual rate steps. Not surprisingly, the bulk of kinetic information is concerned with reactions (228) and (241), and H-Atom transfer from phenols and amines to R02 radicals. However, some data are available for other rate steps involving both unhindered (AH) and hindered (BH) phenols. Some generalized values of these rate coefficients are summarized in Table 25.
