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:
