Extracted text: 12. If carbon dioxide is passed over a bed of graphite at 1050°C, the product-gas stream (assumed to be at equilibrium) is 0.74 mole percent CO, and 99.26 mole percent CO. a) Write a balanced equation for the production of 2 moles of CO from carbon and CO,. b) If the total pressure is 2.00 atm, cal- culate K, and K. for the reaction.
