At high temperatures, a dynamic equilibrium exists between carbon monoxide, carbon dioxide, and solid carbon.

At 900oC, Kc is 0.238.
a. What is the value of Kp?
b. Some carbon dioxide is added to the hot carbon and the system is brought to equilibrium at 900oC. If the total pressure in the system is 6.40 atm, what are the partial pressures of CO and CO2?
c. How will the equilibrium system respond if additional carbon at 900oC is added to the reaction system? Why?
