stituent factors F used to modify these rate constants. The best fit to the data at 298 K are found for the following values (Atkinson, 1997a):

k* = 7.0 X 10~19, F(CH3-) = 1.00, k* = 1.22 X 10" l7, F(-CH2-) = 1.67.

However, this approach is not accurate for branched chain alkanes (Atkinson, 1997).

3. Chlorine Atoms (CI)

Table 6.4 summarizes the rate constants for the reactions of chlorine atoms with alkanes. Structure-reactivity relationships have again been developed for
