(35 pts) Determine the equilibrium constitution (i.e., the amounts, compositions and partial pressures) of the gas and solid phases at equilibrium at 1000°C that begins with a solid powdered mixture

of 1.0 mole CoO and 0.2 mole of graphite, C. The reaction is carried out in a 1 liter fixed volume, therefore also determine the final total pressure. Assume that CO2, CO and O2 are the only gas species possible, and that the gas behaves ideally. Also, assume that C, Co and Co O are the only possible condensed phases and are insoluble in one another. As a strategy towards a quick solution, it is reasonable to assume that the graphite is completely consumed in the reaction. Demonstrate how you would check that this is indeed after you have developed a
