In the chlor-alkali industry chlorine gas is combined with hydrogen gas to produce hydrogen chloride as Cl2g+H2g→           2HClg. If the enthalpy change for this reaction is -185 kJ , calculate the bond enthalpy for the H-Cl bond. Bond enthalpies of Cl-Cl and H-H are 242 kJ mol-1 and 436 kJ mol-1 respectively.
