(1) Reconstruction of the functional dependence of the 2-methylbenzyl hydroperoxide formation rate (RO2H) on the initial dissolved oxygen concentration x from empirical data (points) using (3b) (model optimization with respect to the parameter ) for the o-xylene-oxygen system at 373 K [45] (standard deviation of . (2) Reconstruction of the functional dependence of the total hydrogen peroxide formation rate (H2O2) on the initial dissolved oxygen concentration x from empirical data (symbols) using (3b) and (12) with (model optimization with respect to the parameter α) for the γ-radiolysis of water saturated with hydrogen and containing different amounts of oxygen at 296 K [54] (). The dashed curve described (RO2H) as a function of the initial oxygen concentration x based on (3b) model optimization with respect to α) and the experimental data of curve 2 ().
