The oxidation of SO 2 to SO 3 is an exothermic reaction. The yield of SO 3 will be maximum if:

Options

  1. ATemperature is increased and pressure is kept constant
  2. BTemperature is reduced and pressure is increased
  3. CBoth temperature and pressure are increased
  4. DBoth temperature and pressure are reduced

Correct answer

B. Temperature is reduced and pressure is increased

Step-by-step solution

SO 2 + 1 2 O 2 ⇌ SO 3 ; Δ H = - ve ; Apply Le Chatelier principle.
