Iron can be obtained by reduction of iron oxide `(Fe_3O_4)` with CO according to the reaction :
`Fe_3O_4 + 4CO to 3Fe +4CO_2`
How many kg of `Fe_3O_4` should be heated with CO to get 3 kg iron ?

A

8.12 kg

B

4.14 kg

C

6.94 kg

D

16.8 kg

Text Solution

Verified by Experts

The correct Answer is:
B
`{:(Fe_3O_4,+,4CO,to,3Fe+4CO_2),(232g,,56xx3,=,168):}`
3 moles of iron is produced from 1 mole of `Fe_3O_4.`
168 g of Fe is produced from 232 g `Fe_3O_4.`
3 kg of Fe will be produced by `(232)/(168)xx3000=4142.8` g or 4.14 kg
