At high temperatures, a dynamic equilibrium exists between carbon monoxide, carbon dioxide, and solid carbon. C(s) + CO2(g) = 2 CO(g); ?H° = 172.5 kJ At 900.°C, Kc is 0.238 and Kp is 22.9.
Some carbon dioxide is added to the hot carbon and the system is brought to equilibrium at 900.°C. If the total pressure in the system is 6.38 atm, what are thepartial pressures of CO and CO2? (Dalton's Law: Total Pressure= PCO2 + PCO)
