This equation represents sulfur trioxide being formed in the contact process. $2\text{SO}_2(g) + \text{O}_2(g) \rightleftharpoons 2\text{SO}_3(g) \quad \Delta H = -196\,\text{kJ mol}^{-1}$ What would lower the yield of sulfur trioxide?
- Aaddition of more oxygen
- Ban increase in pressure
- Can increase in temperature
- Dremoval of sulfur trioxide from the reaction chamber
