Question:
The heat of neutralization of a weak acid with strong base is -5.7Kcal. Then find the enthalpy of dissociation of weak acid in kcal.
Answer:
Enthalpy of dissociation of weak acid = Heat of neutralisation of a strong acid with a strong base - Heat of neutralisation of weak acid with a strong base
Consider , Heat of neutralisation of weak acid with a strong base = X
= - 5.7 kcal/mol - (X kcal/mol)
= - 5.7 X kcal/mol
