1.	The bond dissociation energies of gaseous , , and HCl are 104, 58, and 103 kcal/mol respectively. Calculate the energy of formation of HCl gas.
Answer» py:It is DEFINED as the "sum" of "internal energy" and "product" of "pressure and VOLUME".Relation between internal energy and enthalpy is ."Standard enthalpy of formation":The "enthalpy change" when "one mole" of a "substance" in "standard state" is formed from its "CONSTITUENT element" in their standard stateFrom the given,The "bond dissociation energy" of = 104 kcalThe "bond dissociation energy" of = 58 kcalThe "bond dissociation energy" of HCl = 103 kcalThe given CHEMICAL reaction is as follows."
