Popis:	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 9.3×10 9 and 3.3×10 10 dm 3 mol −1 s −1 , respectively. The activation energy was found to be 8.2±0.4 kJ mol −1 (2.0±0.1 kcal mol −1 ). This value is lower than that expected for a diffusion controlled reaction.
