In the reaction \(2CO + O_2 \rightarrow 2CO_2\), we know that each molecule of carbon dioxide (CO₂) contains two carbon-oxygen (C=O) double bonds.
Since there are 2 CO₂ molecules formed, the total bond energy for the 4 C=O double bonds in these 2 molecules is 1,472 kJ.
To find the bond energy of each carbon-oxygen double bond, we divide the total bond energy by the number of double bonds:
\[
\text{Bond energy per C=O bond} = \frac{1,472 \text{ kJ}}{4} = 368 \text{ kJ}.
\]
Therefore, the bond energy of each carbon-oxygen double bond in carbon dioxide is **368 kJ**.

Yes, let's clarify the calculation step by step to confirm the answer.
In the reaction \(2CO + O_2 \rightarrow 2CO_2\):
1. Each molecule of carbon dioxide (CO₂) has **2 C=O double bonds**.
2. Since the reaction produces **2 molecules of CO₂**, the total number of C=O double bonds created is:
\[
2 \text{ (molecules) } \times 2 \text{ (bonds/molecule)} = 4 \text{ C=O bonds}.
\]
3. The total bond energy for all the bonds in **2 CO₂** is given as **1,472 kJ**.
4. To find the bond energy of each C=O bond, we divide the total bond energy by the number of bonds:
\[
\text{Bond energy per C=O bond} = \frac{1,472 \text{ kJ}}{4} = 368 \text{ kJ}.
\]
Thus, the bond energy of each carbon-oxygen double bond in carbon dioxide is indeed **368 kJ**.
