At 1200 K, the approximate temperature of vehicle exhaust gases, Kp for the reaction
2CO2(g) -> 2CO(g) + O2(g)
is about 1*10E-13. Assuming that the exhaust gas (total pressure 1 bar) contains 0.2% CO, 12% CO2 and 3% O2 by volume, is the system at equilibrium with respect to the reaction? Based on your conclusion, would the CO concentration in the exhaust be decreased or increased by a catalyst that speeds up the reaction above?
