Given that the data for neutralization of weak acid (HA) and strong acid is :
`HA+OH^(-)toA^(-)+H_(2)O`, `DeltaH=-41.80 kJ`
`H^(+)+OH^(-)toH_(2)O`, `DeltaH=+ -55.90 kJ`
The enthalpy of dissociation of weak acid would be
A. `-97.20 kJ`
B. `+97.70 kJ`
C. `-14.10 kJ`
D. `14.10 kJ`

Correct Answer - D
Subtract `(ii)` from `(i)` we get,
`HA to H^(+)+A^(-)` , `DeltaH=+14.10kJ`
