ABSTRACT

These inequalities indicate that the species corresponding to x, Y, and z must grow in time scales of the same order of magnitude. The time constants contained in the equations are

and

for respectively P02H, PO; , and p. growth. In the aging conditions under consideration, kb « k t so that Ti » Tp » TO. Thus, because the slowest process governs the whole kinetics, one expects that the time constant characteristic of the autoacceleration is Ti. In other words, the induction time must be sharply related to Ti (as found in the analytical resolution where ti is proportional to K-1 and K-1 == Ti).
