Answer 1

In the reaction \(2CO + O_2 \rightarrow 2CO_2\), each carbon dioxide (CO2) molecule has two carbon-oxygen double bonds. Since the total bond energy of all the bonds in two CO2 molecules is 1,472 kJ, we can find the bond energy of each carbon-oxygen double bond.

Since there are 2 CO2 molecules, there are a total of 4 carbon-oxygen double bonds (2 bonds per CO2).

To find the bond energy of one carbon-oxygen double bond, we divide the total bond energy by the number of bonds:

\[ \text{Bond energy of one C=O bond} = \frac{1,472 , \text{kJ}}{4} = 368 , \text{kJ} \]

So, the bond energy of each carbon-oxygen double bond in carbon dioxide is 368 kJ.
