The toxic gas phosgene decomposes to a limited extent to carbon monoxide and chlorine at 373 K according to the following equation:
COCl2(g) CO(g) + Cl2(g)
The equilibrium constant, Kc, is 2.2 x 10-9 at this temperature.
If a 1.00 L flask is set up with an initial concentration of 0.391 mol/L COCl2, calculate the equilibrium concentration of carbon monoxide in mol/L.
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
