How do the reactivities of NO2 and O3 compare?
« on: 05/12/2011 15:51:14 »
What is the difference between NO2 and O3 in terms of the strengths of their reactivity and oxidising ability?

it's a too generic question.

Ozone is a much more powerful oxidant than nitrogen dioxide, which itself is quite powerful.

How reactive the two substances are really depends

(1) on what else is around to react with, and
(2) on whether you are considering reactivity as a kinetic property (how fast will it react with something?) or a thermodynamic property (how intractable a material will it eventually react with?)

On a textbook scale of oxidation potentials (i.e. only fairly common oxidants listed) ozone comes second to fluorine gas, and a long way ahead of anything else.

Oxygen gas (dioxygen) and chlorine gas (dichlorine) are roughly the same in terms of oxidizing strength. Chlorine gas is slightly better kinetically -- it reacts with things more quickly and under milder conditions. Oxygen gas is a slightly better oxidant thermodynamically: it will oxidize more intractable materials; it will release slightly more energy in oxidizing things. But it usually takes more extreme conditions to get the oxidation reaction started.

It often requires a match (local high temperature) and trace quantities of water vapour to get an oxygen gas oxidation started. Visible light is the usual trigger for a chlorine gas oxidation.
