In which of the following equations can Le-chartelier’s principle be applied?

A. H₂(g)+S(g) → H₂(g)
B. 2H₂S(g) + O₂ (g) → 2H2O(l) + 2SO₂(g)
C. N₂(g) +3H₂(g) → NH₃(g)
D. NaOH(aq) +CO₂(g) → Na₂CO₃(aq) + H₂O(l)
E. S(s) + O₂(g) → SO₂(g)

Correct Answer:

Option C – NaOH(aq) +CO₂(g) → Na₂CO₃(aq) + H₂O(l)
