Essential Chemistry for IGCSE - Chemical Reactions (Section 3 - No. 44)
Which of the following reactions would increase the yield of the product when pressure is increased?
N₂(g) + O₂(g) ⇌ 2NO(g)
2SO₂(g) + O₂(g) ⇌ 2SO₃(g)
2NO₂(g) ⇌ N₂O₄(g)
H₂(g) + I₂(g) ⇌ 2HI(g)
Explanation
In the reaction: 2NO₂(g) ⇌ N₂O₄(g), there are fewer moles on the product side which indicates that the yield will increase if pressure is increased.
