The key step in the synthesis of sulphuric acid is the combustion of SO2 to give sulphur trioxide:

2SO2(g)+O2(g) (yields both ways) 2SO3(g) Keq =5.60Ã104 at 350C

Sulphur dioxide and oxygen are mixed initially at 0.413 and 0.231 bar, respectively, at 350 C. What is the equilibrium partial pressure of SO2 at 350C?
