Figure 10: (a) Temperature dependence of the Ps oxidation reaction rate constant (at an infinite time, ) multiplied by the “initial” concentration of oxidizers in the blob (OH and , see [13, 18] for details). is the sum of and the diffusion coefficient of the oxidizer (OH radical,  cm2/s). The obtained -dependence agrees well with the Stokes-Einstein law, . (b) -dependences of the oxidation reaction radius, , the Ps radius, , and the relative contact density parameter in Ps. is the radius of the oxidizer (approximately, the geometric radius of the OH radical, 1.4 ).
