One of the reaction that takes place in producing steel from iron ore is the reduction of iron(II) oxide by carbon monoxide to give iron metal and CO 2 . FeO s + CO g ⇌ Fe s + CO 2 g ; K P = 0 .265 atm at 1050 K . What are the equilibrium partial pressures of CO and C O 2 respectively at 1050 K if the initial partial pressures are: P c o = 1.4 atm and P C O 2 = 0.80 a t m ?

Options

  1. AP C O = 1.739 a t m a n d P C O 2 = 0.461 a t m
  2. BP C O = 17.39 a t m a n d P C O 2 = 0.461 a t m
  3. CP C O = 1.79 a t m a n d P C O 2 = 0.46 a t m
  4. DP C O = 2.739 a t m a n d P C O 2 = 1.461 a t m

Correct answer

A. P C O = 1.739 a t m a n d P C O 2 = 0.461 a t m

Step-by-step solution

K P = 0.265 = 0.8 - x 1.4 + x On solving, x = 0 .339 ∴ P C O = 1.739 atm and P C O 2 = 0.461 a t m
