Answer 1

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.

Answer 2

are you sure

Answer 3

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.
