Answer:
The number of moles of SO₃ produced by SO₂ are less so it is limiting reactant.
Explanation:
Given data:
Number of moles of SO₂ = 3.1 mol
Number of moles of O₂ = 2.7 mol
Limiting reactant = ?
Solution:
Chemical equation;
2SO₂ + O₂ → 2SO₃
Now we will compare the moles of SO₃ with O₂ and SO₂.
SO₂ : SO₃
2 : 2
3.1 : 3.1
O₂ : SO₃
1 : 2
2.7 : 2×2.7 = 5.4 mol
The number of moles of SO₃ produced by SO₂ are less so it is limiting reactant.
