Use the molar bond enthalpy data in the table to estimate the Average molar bond enthalpies. \( \left(H_{\text {bond }}\right) \) value of \( \Delta H_{\text {ran }}^{\circ} \) for the equation \[ \mathrm{C}_{2} \mathrm{H}_{4}(\mathrm{~g})+\mathrm{HBr}(\mathrm{g}) \longrightarrow \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Br}(\mathrm{g}) \] The bonding in the molecules is shown.
