So this problem has been boggling my mind for a while. If someone could help me out a little that would be AWESOME. Thanks!
The equilibrium conditions for SO2, O2, and SO 3 are important in sulfuric acid production. When a 0.0219 mol sample of SO3 is introduced into an evacuated 1.65 L vessel at 900K, 0.0135 mol SO3 is found to be present at equilibrium. What is the value of Kp for the dissociation of SO3 at this temperature?
Hint: write a balanced chemical equation for the dissociation of SO 3 first.

1. 2SO3 ----> 2SO2 + O2
2. work out moles of SO3 lost
3. this is the same as moles of SO2 gained
4. the moles of O2 gained is half that of the SO2.
5. work out the total number of moles present.
6. work out the mole fraction of each.
7. work out the total pressure in the container, and you're well on the way to working out Kp!
