- The temperature dependence of the rate constant for the reaction between OH radicals and H atoms has been determined in Ar-saturated solutions at pH 2. The reaction was studied in the temperature range 5-233°C. The rate constants at 20°C and 200°C are 9.3×109 and 3.3×1010dm3mol-1s-1, respectively. The activation energy was found to be 8.2±0.4kJmol-1 (2.0±0.1kcalmol-1). This value is lower than that expected for a diffusion controlled reaction. © 2002 Elsevier Science Ltd. All rights reserved.
