Calculate and show the solution of the change in internal energy when 2 moles of CO are converted to 2 moles of CO2 at 1 atm and 25OC.
2CO(g) + O2(g) → 2CO2(g) ∆H = -566.0 kJ/mol
2CO(g) + O2(g) → 2CO2(g) ∆H = -566.0 kJ/mol

-566.0 kJ/mol
• When 2 moles of CO are converted to 2 moles of CO2 at 1 atm and 25°C, the change in internal energy (∆U) is -566.0 kJ/mol. This means that the internal energy decreases by 566.0 kJ for every mole of CO converted to CO2.
