Calculate bond enthalpy (in kJ/mol) of C-Cl in CCl4(g) from the following Data: Δ_vap H°_CCl4 = 30.5 kJ/mol Δ_f H°_(CCl4,l) = -135.5 kJ/mole Δ_a H°(C) = 715 kJ/mol (i.e. enthalpy of atomisation) Δ_a H

Question

Calculate bond enthalpy (in kJ/mol) of C-Cl in CCl4(g) from the following Data:

Δ_vap H°_CCl4 = 30.5 kJ/mol   Δ_f H°_(CCl4,l) = -135.5 kJ/mole

Δ_a H°(C) = 715 kJ/mol  (i.e. enthalpy of atomisation)

Δ_a H°_(Cl2) = 242 kJ/mole
