Question

The volume of H2 at STP required to completely reduce 160grams of Fe2O3

Answer 1

Answer:

The required equation of the given reaction is:-

Fe2O3 + 3CO -----> 2Fe + 3CO2

From the equation we can see that,

1 mole of Fe2O3 -----> 3moles of CO2

Avogadro’s Law states that one mole of any dry gas occupies 22.4L of volume at STP.

So, 3 moles of CO2 would occupy -----> (22.4 * 3) = 67.2L of volume

Hence, 67.2L of CO is needed for 1 mole of Fe2O3 to be reduced completely.
