B) $ \Delta H $ is negative for endothermic reaction
C) The heat of neutralization of strong acid and strong base is always the same
D) The enthalpy of fusion is negative
Show Answer
Answer:
Correct Answer: C
Solution:
$ \Delta H=-ve $ for exothermic reaction. $ \Delta H=+ve $ for endothermic reaction Enthalpy of fusion is + ve.
