Consider the reaction 4FeS2 + 11O2 → 2Fe2O3 + 8SO2. If 8 moles of FeS2 react with 15 moles of O2, what is the limiting reactant? (3 points) Select one:

a. FeS2

b. Fe2O3

c. O2

d. SO2

Explanation:

4FeS₂ + 11O₂ → 2Fe₂O₃ + 8SO₂.

4 moles of FeS₂ reacts with 11 moles of O₂

8 moles of FeS₂ reacts with 22  moles of O₂

Moles of O₂ available is 15 .

So O₂ is in short supply .

So O₂ is the limiting reagent.

Option (c) is the right choice.
