How many moles of Iron (Fe) can be produced form 20 moles of carbon (C)?
2Fe2O3 + 3C —— 4Fe + 3C02

Moles of Fe produced = 40 moles

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
