The reversible reaction of sulfur dioxide and oxygen to form sulfur trioxide is shown below.
2SO2(g)+O2(g)⇌2SO3(g) 2\text{SO}_2(\text{g}) + \text{O}_2(\text{g}) \rightleftharpoons 2\text{SO}_3(\text{g}) 2SO2(g)+O2(g)⇌2SO3(g)An equilibrium mixture contains 1.6 mol SO21.6\text{ mol }\text{SO}_21.6 mol SO2, 0.8 mol O20.8\text{ mol }\text{O}_20.8 mol O2, and 1.6 mol SO31.6\text{ mol }\text{SO}_31.6 mol SO3. The total pressure is 200 atm200\text{ atm}200 atm.
