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 2.32 atm CO(g) and excess FeO(s) react in a sealed container at 1000°C? PCO atm PCO2 atm
Ferrocene cannot be nitrated using the conventional HNO3-H2SO4 mixed acid conditions, even though nitration is an electrophilic
