Taking into account the reaction stoichiometry, 4 moles of FeO are produced of 8 moles of SO₂ are produced.
Reaction stoichiometry
In first place, the balanced reaction is:
2 CuFeS₂ + 5 O₂ → 2 Cu + 2 FeO + 4 SO₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- CuFeS₂: 2 moles
- O₂: 5 moles
- Cu: 2 moles
- FeO: 2 moles
- SO₂: 4 moles
Moles of FeO formed
The following rule of three can be applied: if by stoichiometry of the reaction 4 moles of SO₂ are produced together with 2 moles of FeO, 8 moles of SO₂ are produced together with how many moles of FeO?
[tex]moles of FeO=\frac{8 moles of SO_{2}x2 moles of FeO }{4 moles of SO_{2}}[/tex]
moles of FeO= 4 moles
In summary, 4 moles of FeO are produced of 8 moles of SO₂ are produced.
