Calculate the standard enthalpy change of the reaction of 2 moles of carbon monoxide and 1 mole of oxygen gas to form 2 moles of carbon dioxide gas, given that the enthalpy change for the decomposition of 2 moles of carbon dioxide to 2 moles of carbon monoxide and 1 mole of oxygen gas is -566 kJ/mol, and the enthalpy change for the combustion of 1 mole of carbon to form carbon dioxide gas is -394 kJ/mol. Use Hess's Law to solve the problem.
