In the production of SO3 from SO2 and oxygen, the yield of SO3 is increased by
Correct answer: B. Adding more SO2
- A. Adding a catalyst
- B. Adding more SO2
- C. Increasing temperature
- D. Removing oxygen
Explanation
Increasing the concentration of SO₂ or O₂ can also push the reaction toward producing more SO₃.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
