Using the values of bond energy from the table below, estimate the enthalpy change for the following reaction: \[ \mathrm{N}_{2}(g)+2 \mathrm{O}_{2}(g) \rightarrow 2 \mathrm{NO}_{2}(g) \] \[ \Delta H_{\text {rxn }}=\quad \mathrm{kJ} \] The enthalpy change for the following reaction is \( -318 \mathrm{~kJ} \). Using bond energles, estimate the \( \mathbf{O}-\mathrm{F} \) bond energy in OF \( _{2}(\mathrm{~g}) \). \[ \mathrm{OF}_{2}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \longrightarrow \mathrm{O}_{2}(\mathrm{~g})+2 \mathrm{HF}(\mathrm{g}) \] \( \mathrm{kJ} / \mathrm{mol} \) The enthalpy change for the following reaction is \( -137 \mathrm{~kJ} \). Using bond energies, estimate the \( \mathrm{C}-\mathrm{C} \) bond energy in \( \mathrm{C}_{2} \mathrm{H}_{6}(g) \). \[ \mathrm{C}_{2} \mathrm{H}_{4}(g)+\mathrm{H}_{2}(g) \rightarrow \mathrm{C}_{2} \mathrm{H}_{6}(g) \] Bond energy \( =\quad \mathrm{kJ} / \mathrm{mol} \)
