The contact process involves the reversible oxidation of sulfur dioxide to sulfur trioxide as 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)In an equilibrium mixture, the partial pressure of SO2\text{SO}_2SO2 is 2.0 atm2.0\text{ atm}2.0 atm and the partial pressure of O2\text{O}_2O2 is 5.0 atm5.0\text{ atm}5.0 atm. The total pressure of the system at equilibrium is 11.0 atm11.0\text{ atm}11.0 atm.
