Consider the following chemical reaction : aFe2O3(s) + bCO(g) + cFe(s) + dCO2 In the balanced chemical equation of the above, which of the following will be the values of the coefficients a, b, c and d respectively?

Correct Answer: 1, 3, 2, 3

Explanation:

Fe2O3 + 3CO = 2Fe + 3CO2


Hematite + Carbon Monoxide = Iron + Carbon Dioxide


In this reaction, the iron oxide is reduced to iron, and the carbon is oxidised to carbon dioxide.
