Answer:
5.25 moles of carbon monoxide are required.
Explanation:
[tex]Fe_2O_3(s) + 3CO(s)\rightarrow 2Fe(l) + 3CO_2(g)[/tex]
Moles of of iron (iii) oxide = 1.75 moles
According to reaction , 1 mole of iron (iii) oxide reacts with 3 moles of carbon monoxide.
Then 1.75 mol of iron (iii) oxide will react with :
[tex]\frac{3}{1}\times 1.75 mol=5.25 mol[/tex] of iron (iii) oxide
5.25 moles of carbon monoxide are required.
The number of mole of CO required to react with 1.75 moles of Fe₂O₃ is 5.25 moles
We'll begin by writing the balanced equation for the reaction. This is given below:
Fe₂O₃ + 3CO —> 2Fe + 3CO₂
From the balanced equation above,
1 mole of Fe₂O₃ reacted with 3 moles of CO.
With the above information in mind, we can obtain the number of mole of CO required to react with 1.75 moles of Fe₂O₃. This can be obtained as follow:
From the balanced equation above,
1 mole of Fe₂O₃ reacted with 3 moles of CO.
Therefore,
1.75 moles of Fe₂O₃ will react with = 3 × 1.75 = 5.25 moles of CO.
Thus, 5.25 moles of CO is required for the reaction.
