kM
£ 3 x 104 dm3mol-1s-1
kM derived from
l0 in the pure alcohol assuming "concentration
" of pure alcohol of 24.7M

Interact, 1979¸ 6, 413.
A = 2.5 x 109 dm3mol-1s-1
Ea = 34.4 kJ mol-1
c. Ito, Y., Ng, B.W., Jean,
Y.C. and Walker, D.C. Can. J. Chem., 1980, 58, 2395.
kM = 3 x 104 dm3mol-1s-1
KIE = kM / kH
= 3 x 104 / 2.8 x 106 » 0.01
kH = 2.6 x 106
dm3mol-1s-1 average of 2 values from:
www.rcdc.nd.edu/compilations/HAtom/H.htm
and recently kH =
(2.84 ± 0.07) x 106 dm3mol-1s-1
log(A/dm3mol-1s-1) = 11.64 ± 0.17
Ea = (29.4 ± 0.8) kJ
mol-1 for T = 283 K to 359 K
