J. Phys. Chem., 1983,
87, 841.
Reaction: NCCH2COO- +
Mu ®
MuNCCH2COO-
Type of reaction: addition across
cyanide bond
kM = 7.7 x 107 dm3mol-1s-1
pH not given
Ea = (35 ± 2) kJ mol-1
for T = 273 K to 353
B = 3.1 x 1011 dm3mol-1s-1
B – preexponential factor in
the equation ln(kM/T1/2)
= lnB – E/RT
KIE = kM / kH
= 7.7 x 107 / 2.9 x 106 = 26
kH = 2.9 x 106
dm3mol-1s-1 for cyanoacetic acid at pH = 1.0
