A) less than \[-57.33\,kJ\,mo{{l}^{-1}}\]
B) \[-57.33\,kJ\,mo{{l}^{-1}}\]
C) greater than \[-57.33\,kJ\,mo{{l}^{-1}}\]
D) \[-57.33\,kJ\,mo{{l}^{-1}}\]
Correct Answer: A
Solution :
Heat of neutralization of strong acid and strong base is -57.33 kJ. MgO is weak base while HCl is strong acid, so the heat of neutralization of MgO and HCl is lower to -57.33 kJ because MgO requires some heat in ionisation, then net released amount of heat is decreased.You need to login to perform this action.
