“…In the basic solution, the difference is higher, about 30%. This result fits well with the results reported by Benson and Axworthy (1959). These values agree with the absorb curves, which support a 20% lower reactivity for ozone produced with high voltage (if we assume the absorb curves directly represent the reactivity).…”

“…Ozone decomposition in gas phase was found (Limvorapituk, 1991) to be a secondorder reaction, instead of a first-order, with solid media and thus is in agreement with previous research (Benson andAxworthy, 1959, andKirk-Othmer, 1967). The second-order rate constant was obtained by taking tangents at various points on a Downloaded by [Columbia University] at 11:51 08 December 2014 conversion of ozone concentration [(l+e)X/(l-X) + eLn(l-X)] vs influent ozone concentration multiplied by the detention time (C M *t).…”

“…Ellis and Tometz (1971) Schumacher et al (1938) found that when a small amount of ozone was mixed in a large quantity of oxygen, a homogeneous second-order ozone decomposition should occur. Benson and Axworthy (1959) studied the mechanism of ozone decomposition in the gas phase. Adding oxygen to pure ozone accelerates its rate of decomposition, while adding oxygen to dilute ozone inhibits its rate of decomposition.…”

“…Adding oxygen to pure ozone accelerates its rate of decomposition, while adding oxygen to dilute ozone inhibits its rate of decomposition. Adding foreign gases to pure oxygen, e.g., N 2 or CO 2 , accelerated the rate, while their addition to dilute ozone has no effect (Benson and Axworthy, 1959). Reaction of ozone decomposition in the gas phase is a second-order homogeneous reaction.…”

Ozone decomposition kinetics are investigated together with the influence of energy input to an ozone generator. Decomposition is considered in a solid bed reactor, a gas phase reactor and a bubbling reactor. Ozone is produced at the same concentration and gas flow rate using two methods: 1) from the generator at a higher power giving higher ozone concentration, then ozone is diluted by oxygen before entering the decomposition reactor, and 2) at a lower power without dilution.A clear effect of the energy power density on the ozone generation is shown.

Reaction (2) also has been suggested as the source of ozone in gas discharges [Benson and Axworthy, 1959;Benson, 1959]. The identity of the 02* state has been variously ascribed to vibrationally hot O2 in the ground electronic state [Volman, 1954[Volman, , 1956 O (9 x 10-a2 cm-3 s -a) and 02 (2.9 x 10-a3 cm-3 s-a).…”

The simultaneous measurements of atomic O, O2, O3, and N2 between 90 and 110 km obtained by a rocket‐borne mass spectrometer flown during the Aladdin 74 program provide an opportunity to test directly the simple atmospheric chemical model first proposed more than 50 years ago by S. Chapman, which is today the core of the complex chemistry controlling stratospheric O3. The Aladdin 74 O3 results are found to be significantly in excess of model abundances computed using the most current values of the key chemical parameters. The calculations may possibly be in error due to uncertainties in these key parameters and/or in the measurement of the related species. However, the extra O3 may be a consequence of reactions between ground state O2 and electronically excited O2 resulting from the recombination of atomic O.
