### Understanding Bond Dissociation Energy in CO₂ Molecules The question prompts us to determine the energy required to break two bonds in one mole of carbon dioxide (CO₂) molecules. The concept of bond dissociation energy is critical in understanding the strength of chemical bonds in different molecular structures. #### Bond Dissociation Energy Table The table provides bond dissociation energies for various single and multiple bonds between common elements. All values are expressed in kilojoules per mole (kJ/mol). ##### Single Bonds - **H-H**: 432 - **H-C**: 411 - **H-N**: 386 - **H-O**: 459 - **C-C**: 346 - **C-N**: 305 - **C-O**: 358 - **N-N**: 167 - **N-O**: 201 - **O-O**: 142 ##### Multiple Bonds - **C=C**: 602 - **C≡C**: 835 - **C=O**: 799 - **C≡N**: 887 - **N=N**: 409 - **N≡N**: 942 - **O=O**: 494 Given the context of CO₂, the molecule features two carbon-oxygen double bonds (C=O). According to the table, each C=O double bond has a dissociation energy of 799 kJ/mol. #### Answering the Question To find the total energy to break both C=O bonds in CO₂, you calculate: \[ \text{Energy required} = 2 \times 799\, \text{kJ/mol} = 1598\, \text{kJ/mol} \] Thus, 1598 kJ/mol is needed to dissociate two C=O bonds in 1 mole of CO₂ molecules. Understanding and calculating bond dissociation energy helps predict reaction behavior and bond stability in chemical processes.

Expert Solution
Step 1
bond dissociation energy is the energy required to break the bonds in a molecule.
given: CO2 molecule
O=C=O
we have to break the 2 bonds in a molecule ]
since C=O has 2 bonds, we have to break this bonds,
the data is given for this breaking of C=O bonds is 799 kJ/mol
