Free radical research communications, 1993•Taylor & FrancisThe rate constant for the reaction of NO with· O2− was determined to be (6.7±0.9)× 109 1
mol− 1 s− 1, considerably higher than previously reported. Rate measurements were made
from pH 5.6 to 12.5 both by monitoring the loss of· O2− and the formation of the product−
OONO. The decay rate of− OONO, in the presence of 0.1 moll− 1 formate, ranges from 1.2 s−
1 at pH 5 to about 0.2 s− 1 in strong base, the latter value probably reflecting catalysis by
formate.
