Answer : The number of moles of CO react with one mole of [tex]Fe_2O_3[/tex] are, 3 moles.
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
The balanced chemical reaction will be:
[tex]Fe_2O_3+3CO\rightarrow 2Fe+3CO_2[/tex]
By Stoichiometry of the reaction:
1 mole of [tex]Fe_2O_3[/tex] reacts with 3 moles of [tex]CO[/tex] to produce 2 moles of iron and 3 moles of [tex]CO_2[/tex].
So, we can say that 1 mole of [tex]Fe_2O_3[/tex] reacts with 3 moles of [tex]CO[/tex].
Hence, the number of moles of CO react with one mole of [tex]Fe_2O_3[/tex] are, 3 moles.
