Moles of Fe produced = 40 moles
Further explanation
Given
Reaction
2Fe2O3 + 3C —— 4Fe + 3C02
20 moles of C
Required
moles of Fe
Solution
The reaction coefficient in a chemical equation shows the mole ratio of the reacting compounds (reactants and products)
From the reaction, mol ratio of Fe : C = 4 : 3, so mol Fe :
= 4/2 x mol C
= 4/2 x 20
= 40 moles
