At 1200 K The Approximate Temperature Of Automobile Exhaust Gases

At 1200 K, the approximate temperature of automobile exhaust gases (Figure 15.15), Kp for the reaction
At 1200 K, the approximate temperature of automobile exhaust gases

Is about 1 × 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?
