Determination of the Rate Constants of the Reactions CO2 +OH— HCO3— and Barbituric Acid → Barbiturate Anion+H+ Using the Pulse Radiolysis Technique

Abstract

The kinetics of the reactions of CO2 + OH- ->HCO3- (i) and barbituric acid →barbiturate anion + H+ (ii) have been remeasured using as a new approach the pulse radiolysis technique with optical and conductivity detection. The rate constants obtained in the present study, ki (21 °C) = 6900 ± 700 M-S-1 and ku (19 °C) = 22 ± 2 s1 agree within experimental errors with values obtained earlier by other methods. © 1982, Walter de Gruyter.
