Re-evaluation of the rate constant for the H atom reaction with tert-butanol in aqueous solution

Abstract The rate constant ( k ) of the H+ tert -butanol reaction at pH∼1–2 was measured by the time profile of the absorbance build-up of the tert -butanol radical and by competitive reactions for H atoms between maleic acid and tert -butanol. The determined rate constant, k =(1.15±0.2)×10 6  mol −1  dm 3  s −1 , is nearly an order of magnitude higher than the previously published rate constants.
