SO2 oxidation w/o a catalyst

I am interested in the rate at which SO2 oxidizes to SO3 in the absence
of a catalyst. It seems like this ought to be a well known and
researched reaction. I know that at lower temperatures (below ~600) SO3
is favored and at higher temperatures SO2 is favored. Specifically,
what happens if I put SO2 with an excess of O2 into a plug flow reactor
(no catalyst, no photons) what will the conversion be? So far
everything I have seen is either about a sulfuric acid plant or photo
catalyzed in the Earth's or Venus's atmosphere.

Can anyone point me in the right direction?

Thanks

Well U need to check basics of Gibbs energy for this reaction and then
u can find out the probable temperature range at which this reaction is
theoretically possible w/o catalyst.

However, it doesnt give u the rate of reaction but luckiest thing is
that u have suffciient data available on this reaction for the
parameters required to calculate the rate of reaction.
