Consider the following set of reactions :
`CHCl_(2)COOH+NaOHrarrCHCl_(2)COONa+H_(2)O " " Delta H_(1) = - 12830` Cal.
`HCl + NaOH rarr NaCl + H_(2)O " " DeltaH_(2) = - 13680` Cal.
`NH_(4)OH + HCl rarr NH_(4)Cl + H_(2)O" " Delta H_(3) = - 12270` cal.
Select the correct option (s) :
A. Enthalphy of neutralization of `CHCl_(2)COOH`by`NH_(4)OH`is `11420` Cal.
B. Enthalphy of dissociation of `CHCl_(2)COOH = - 850` Cal.
C. Enthalphy of dissociation of `NH_(4)OH = 1410`Cal.
D. Enthalphy change for the reaction `H_(2)O rarr H^(+) + OH^(-)` is `-13680`Cal.
