For the reaction Fe ₂ O ₃+3 CO 2 Fe +3 CO ₂ , the volume of carbon monoxide required to reduce one mole of ferric oxide is

Options

  1. A22.4 dm ³
  2. B44.8 dm ³
  3. C67.2 dm ³
  4. D11.2 dm ³

Correct answer

C. 67.2 dm ³

Step-by-step solution

1 ~mol Fe ₂ O ₃ +3 3 ~mol 3 CO 2 Fe +3 CO ₂ Volume of 1 mole carbon monoxide =22.4 ~L (at STP) 1 mole of ferric oxide is reduced by =3 moles of CO =3 22.4 ~L of CO =67.2 dm ³ of CO
