Calculate the enthalpychange for the process: \( \quad \mathrm{CCl}_{4}(\mathrm{~g}) \rightarrow \mathrm{C}(\mathrm{g})+4 \mathrm{Cl}(\mathrm{g}) \) and Calculate bond enthalpy of C- \( -\mathrm{Cl}_{\text {in }} \mathrm{CCl}_{4}(\mathrm{~g}) \)
\( P \)
Given : \( \Delta_{\text {vap }} \mathrm{H}^{\circ}\left(\mathrm{CCl}_{4}\right)=30.5 \mathrm{~kJ} \mathrm{~mol}^{-1}, \Delta \mathrm{H}^{\circ}\left(\mathrm{CCl}_{4}\right)=-135.5 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
W. \( \Delta \mathrm{H}^{\circ}(\mathrm{C})=715.0 \mathrm{~kJ} \mathrm{~mol}^{-1} \) where \( \Delta_{\mathrm{a}}^{\mathrm{f}} \mathrm{H}^{\circ} \) is enthalpy of atomisation \( \Delta \Delta_{\mathrm{a}}^{\mathrm{a}} \mathrm{H}^{\circ}\left(\mathrm{Cl}_{2}\right)=242 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
