2SO2 (g) + O2(g) ? 2SO3(g)
The formation of SO3 from SO2 andO2 is an intermediate step in the manufacture of sulfuric acid, and it is also responsible for the acid raid phenomenon. The equilibrium constant (Kp) for the reaction is0.13 at 830οC. In one experiment 2.00 moles ofSO2 and 2.00 moles of O2 were initially present in a flask. Explain what must the total pressure is at equilibrium to have an 80.0 percent yield of SO3?
