In the reaction provided:

\[ 2 \text{CO} + \text{O}_2 \rightarrow 2 \text{CO}_2 \]

Given that the total bond energy of all the bonds in carbon dioxide (CO2) is 1,472 kJ, this energy corresponds to the bonds in 2 molecules of CO2, since there are 2 moles being produced.

To find the bond energy of each carbon-oxygen double bond in a single CO2 molecule, we can divide the total bond energy by the number of CO2 molecules produced:

\[ \text{Bond energy per CO}_2 \text{ molecule} = \frac{1,472 \text{ kJ}}{2} = 736 \text{ kJ} \]

Therefore, the bond energy of each carbon-oxygen double bond in carbon dioxide is 736 kJ.
