Converting sulphur dioxide into sulphur trioxide.

**janelee** · 07-15-2008, 08:08 PM

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...

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

I think Janelee needs to do his/her own chemistry homework...

You're only hurting yourself by cheating!

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