The heats of neutralisation of four acids`A,B,C` and `D` are `-13.7,-9.4,-11.2` and `-12.4kcal` respectively, when they are neturalised by a common base. The acidic character obeys the order `:`

The heats of neutralisation of four acids A, B, C, D are -13.7, -9.4, -11.2 and -12.4 kcal respectively when they are neutralised by a common base. The acidic character obeys the order:

The heats of neutralisation of four acids A, B, C and D are 13.7, 9.4, 11.2 and 12.4 kcal respectively when they are neutralised against a common base. The weakest acid among A,B,C and D is-

The heats of neutralisation of four acids a , b , c and d when neutralised against a common base are 13.7 , 9.4 , 11.2 and 12.4 kcal respectively. The weakest among these acids is

A solubility contains one mole each of HA and HB (both are weak acids) in one litre solution. Now 1 mole of NaOH is added to this solution so that both the acids are partly neutralised. Heat of neutralisation for HA and HB are- 11.8 and- 12.4 kcal respectively and the heat produced during partial neutralisation of HA and HB is- 12.25 kcal. The ratio of dissociation constant of two acids are:
