Question

when 5 moles of ion oxide react with 25 moles of carbon monoxide what is the moles of the product formed when one of the reagents is used in excess

Answer 1

Answer: 25 moles of product are formed.

Step-by-step explanation:

The balanced chemical equation will be :

`Fe_2O_3+3CO\rightarrow 2Fe+3CO_2`

According to stoichiometry :

1 mole of
`Fe_2)_3` require = 3 moles of
`CO`

Thus 5 moles of
`Fe_2O_3` will require=
`(3)/(1)* 5=15moles` of
`CO`

Thus
`Fe_2O_3` is the limiting reagent as it limits the formation of product and
`CO` is the excess reagent.

As 4 moles of reactant give = 5 moles of product

Thus 20 moles of reactants will give =
`(5)/(4)* 20=25moles` of products
