A 1.604 g sample of methane (CH4) gas and 6.400 g of oxygen gas are sealed in a 2.50 L vessel at 411 C and are allowed to reached equilibrium. Methane can react with oxygen to form gaseous carbon dioxide and water vapor, or methane can react with oxygen to form gaseous carbon monoxide and water vapor. At equilibrium the pressure of oxygen is 0.326 atm, and the pressure of water vapor is 4.45 atm. Calculate the pressures of carbon monoxide and carbon dioxide at equilibrium.
