When gaseous phosphorus pentachloride is heated, it breaks down to form gaseous phosphorus trichloride and chlorine. The table lists the bond energies. Bond energies: $\text{P-Cl}$ (in both chlorides): $330\,\text{kJ mol}^{-1}$ $\text{Cl-Cl}$: $242\,\text{kJ mol}^{-1}$ What is the enthalpy change for the decomposition of $\text{PCl}_5$ into $\text{PCl}_3$ and $\text{Cl}_2$?
- A$-418\,\text{kJ mol}^{-1}$
- B$-88\,\text{kJ mol}^{-1}$
- C$+88\,\text{kJ mol}^{-1}$
- D$+418\,\text{kJ mol}^{-1}$
