When 100 mL of IM HCl was mixed with 100 mL of 1 0 M NaOH in an isolated beaker at constant pressure a temperature increase of 5 7 C was measured for the beaker and its contents expt 1 Because the enthalpy of neutralisation of a strong acid with a strong base is constant 57 0 kJ mot this experiment could be used to measure the calorimeter constant In a second experiment Expt 2 100 mL of 2M acetic acid K 2 10 5 was mixed with 100 mL of 1M NaOH under identical condition to Expt 1 where a temperature rise of 5 6 C was measured Consider heat capacity of all solutions as 4 2 J gm K and density of all solutions as 1 gm mL Enthalpy of dissociation in kJ mot of acetic acid obtained in the Expt 2 is A 1 B 10 C 24 5 D 51 4
