One of the ways to produce iron is to take iron(II) oxide and react it with carbon monoxide to get pure iron and carbon dioxide. The reaction is FeO(s) + CO(g) = Fe(s) + CO2(g). What is the partial pressure of CO2(g) if 2.00 atm of CO and excess iron(II) oxide are used to initiate the reaction? The Keq for this reaction is 0.800 at 1000 C, which is the typical temperature for this type of reaction.

Answer 1

........FeO(s) + CO(g) = Fe(s) + CO2(g)
I......solid....2.00......solid..0
C......solid......-x......solid..x
E......solid....2.00-x....solid..x

Keq = pCO2/pCO = 0.800
Substitute the E line into Keq and solve for x and 2.00-x

Answer 2

is it 2.5
