At 1200 K, the approximate temperature of automobileexhaust gases , Kp for the reaction2 CO2(g) ⇌ 2 CO(g) + O2(g)is about 1 x 10-13. Assuming that the exhaust gas (totalpressure 1 atm) contains 0.2% CO, 12% CO2, and 3% O2by volume, is the system at equilibrium with respect to theCO2 reaction? Based on your conclusion, would the COconcentration in the exhaust be decreased or increased bya catalyst that speeds up the CO2 reaction? Recall that at afixed pressure and temperature, volume % = mol %.

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