Question

For SO₂ + ½O₂ → SO₃, if 2 mol SO₂ and 0.5 mol O₂ are present, moles of SO₃ produced are:
  1. A
    0.5 mol
  2. B
    1 mol
    Correct
  3. C
    1.5 mol
  4. D
    2 mol

Correct answer

1 mol

Explanation

O₂ needed for 2 mol SO₂ = 1 mol, but only 0.5 mol available → O₂ limits. SO₃ = 2×0.5 = 1 mol.
