For the reaction SO 2 ( g ) + 1 2 O 2 ( g ) ⇌ SO 3 ( g ) , the percentage yield of product at different pressures is shown in the figure. Then, which among the following is true?
Options
- APressure has no effect
- BP 1 < P 2 < P 3
- CP 1 > P 2 > P 3
- DP 1 = P 2 = P 3 ≠ 0
Correct answer
C. P 1 > P 2 > P 3
Step-by-step solution
So according to the concept of equilibrium reaction which is SO 2   + 1 2 O 2   ⇌   SO 3 this reaction is favoured as exothermic reaction When pressure is lowered, the forward reaction is favoured. This increases the yields of SO 3 So according to the question graph this will be possible when P 1 > P 2 > P 3
