        The heat released in neutralisation of HCL and NaOH is 13.7kcal/mol, the heat released on neutralisation of NaOH with CH3COOH is 3.7 kcal/mol.

The delta H' of ionistion of CH3COOH is?

										In the neutralization process ions come to each other and form  salt and water.
 HCL is strong acid means  H+ + CL-
and NaOH is strong base means   Na+  + OH-

So there is not any energy loss to break HCL or NaOH. total energy will come as neutralisation.

In Case of NaOH + CH3COOH
NaOH is  strong base means   Na+  + OH-
But CH3COOH is a weak acid so have to give some energy to form CHCOO-  + H+  

So total released energy== total energy in case of (strong acid + strong base) - energy require to form ions.

3.7 = 13.7 - energy require to form ions
energy require to form ions= 10.00 kcal.

only CH3COOH is weak nature

So this enegy is ionisation energy of CH3COOH
