Answer 1

In the reaction \( 2CO + O_2 \rightarrow 2CO_2 \), carbon dioxide (CO₂) has a total bond energy of 1,472 kJ.

Each molecule of carbon dioxide contains 2 carbon-oxygen double bonds. Therefore, to find the bond energy for each carbon-oxygen double bond, you would divide the total bond energy by the number of double bonds:

\[ \text{Bond energy of each double bond} = \frac{1,472 \text{ kJ}}{2} = 736 \text{ kJ} \]

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