Answer:

Number of moles of Fe = 10 mol

Number of moles of CO₂ = 15 mol

Explanation:

Given data:

Number of moles of iron oxide = 5 mol

Number of moles of carbon monoxide = 25 mol

Number of moles of product = ?

Solution:

Fe₂O₃ + 3CO   →  2Fe + 3CO₂

Now we will compare the moles of reactant with product.

                  Fe₂O₃        :         Fe

                     1             :          2

                    5             :         2×5 = 10 mol

                Fe₂O₃        :         CO₂

                     1             :          3

                    5             :         3×5 = 15 mol

                  CO           :         Fe

                     3             :          2

                    25             :         2/3×25 = 16.7 mol

                  CO            :         CO₂

                     3             :          3

                    25             :         25

Less number of moles of Fe and CO₂ are formed by iron oxide thus it will act as limiting reactant while CO is inn excess.
