Question

A key step in the extraction of iron from its ore is shown below.

This step occurs in the 700? to 1200?C zone within a blast furnace. What are the equilibrium partial pressures of CO(g) and CO2(g) when 1.52 atm CO(g) and excess FeO(s) react in a sealed container at 1000?C?

A key step in the extraction of iron from its ore is shown below. FeO(s) + CO(g) Fe(s) + CO2(g) Kp = 0.403 at 1000 C This step occurs in the 700 to 1200 C zone within a blast furnace. What are the equilibrium partial pressures of CO(g) and CO2(g) when 1.52 atm CO(g) and excess FeO(s) react in a sealed container at 1000 C? PCO_____ PCO2_________

Explanation / Answer

FeO(s) + CO(g) ===>Fe(s) + CO2(g

At equilibrium partial pressure CO = 1.52 - x and partial pressure CO2 = x

0.403 = x / 1.52-x

0.403*1.52 - 0.403 x = x

0.61526 = 1.403 x

x = 0.436 atm

partial pressure CO2 =0.436 atm<<<<<<<<<<<<<answer

1.52- 0.436 = 1.083 atm

partial pressure CO=1.083 atm <<<<<<<<<<<<<,answer
