(1 point) Responses 2,944 kJ 2,944 kJ 368 kJ 368 kJ 736 kJ 736 kJ 1,472 kJ 1,472 kJ

Answer 1

In the reaction \( 2CO + O_2 \rightarrow 2CO_2 \), two molecules of \( CO_2 \) are produced, and each \( CO_2 \) molecule contains two carbon-oxygen double bonds.

The total bond energy of all the bonds in the two \( CO_2 \) molecules is given as 1,472 kJ. Since there are two \( CO_2 \) molecules, the total bond energy for one molecule of \( CO_2 \) is:

\[ \frac{1,472 \text{ kJ}}{2 \text{ (for 2 molecules of CO}_2)} = 736 \text{ kJ} \]

Since each \( CO_2 \) molecule has 2 carbon-oxygen double bonds, the bond energy for each carbon-oxygen double bond is:

\[ \frac{736 \text{ kJ}}{2} = 368 \text{ kJ} \]

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