It is known that entropy of neutralisation of a strong acid and strong base is -13.68kcal/mol.If enthalpy of neutralisation of N_2H_4(hydrazine) with strong acid is equal to -11.68 kcal/mol, then enthalpy of the reaction N_2H_4+H_2OtoN_2H_5^+(aq)+OH^(-)(aq) in Kcal/mol is : |

Answer» ENTHALPY of neutralisation is less than-13.68 kcal/mol, because some ENERGY is CONSUMED for ionisation `:. DeltaH_("ion")=13.68-11.68=2` kcal/mol |
