Converting sulphur dioxide into sulphur trioxide.

[janelee]

Can anyone explain how sulphur dioxide converts into sulphur trioxide? Specifically, I'd like to understand how to reduce the rate of sulphur dioxide converting into sulphur trioxide.

SO2(g) + 1/2 O2(g)<-> SO3 (g) H= -99.2 kJ

it appears to be an equilibrium equation, so by changing the stresses on the system you should be able to favor the reverse direction. High heat, low pressure environment should push SO3 to break down into SO2 and O2

Not sure it's that simple SirJac...

there's a patent about there using an oxidizing agent to do it (To view links or images in this forum your post count must be 2 or greater. You currently have 0 posts.)

I'm sure there are other oxidizing agents used...maybe try "oxidation of sulphur dioxide".

Or Janelee might be working on a revolutionary chemical weapon...
