Аннотация: The value of effective activation energy of the dark reaction on Pd wire for 2H2 + O2 reaction at 80 Torr has been estimated as 4.1 ± 1 kcal mol–1 that is characteristic of a surface process. It was demonstrated that at pressures up to 200 Torr, the rate of chain termination determines the critical diameter value in the flame penetration through Pt and Pd cylinders. The efficiency of Pd surface in the chain termination reaction was found much greater than that of Pt.

Ключевые слова: flame, penetration, palladium, platinum, cylinders, activation energy, chain, termination.
