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 neutralisation of strong acid and strong base is -57.33 kJ. MgO is a weak base while HCl is a strong add, so the heat o neutralisation of MgO and HCl is lower than -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.
