Chemistry - Thermochemistry Question with Solution | TestHub

Find bond enthalpy of $\mathrm{C}=\mathrm{O}$ (in $\mathrm{kJ}/\mathrm{mol}$) using the following information:

$\Delta H_{atomisation}[\mathrm{C}(\mathrm{s})]=700kJ/mol$

$\Delta H_f[\mathrm{C}{\mathrm{O}}_2(\mathrm{g})]=–400kJ/mol$

${\mathrm{BE}}_{\mathrm{O}=\mathrm{O}}=500kJ/mol$

Resonance energy of $\mathrm{C}{\mathrm{O}}_2=–150kJ/mol$
