A tentative model for the inhibition and the enhancement of the Ps formation in mixtures of two compounds

In order to explain the so called inhibition of o-Ps formation by certain solutes, a model based on the hypothesis of hot reactions between the o-Ps atoms and the solute molecules has been proposed in previous papers. From this model an equation was derived which not only describes rather well the dependence of the o-Ps survival probability on the inhibitor concentration, but allowed some predictions which were experimentally verified. In the present paper it is reported that the equation mentioned above is a particular solution of a more comprehensive equation which can account, in principle at least, for the general problem of Ps formation in any system of two components.
