PARAGRAPH-2
(19 & 20)
When 100 mL of 1.0 M HCl was mixed with 100 mL of 1.0 M NaOH in an insulated beaker at constant pressure, a temperature increase of 5.7 ºC was measured for the beaker and its contents (Expt. 1). Because the enthalpy of neutralization of a strong acid with a strong base is a constant (–57.0 kJ mol−1), this experiment could be used to measure the calorimeter constant. In a second experiment (Expt. 2), 100 mL of 2.0 M acetic acid (Ka = 2.0 × 10–5) was mixed with 100 mL of 1.0 M NaOH (under identical conditions to Expt. 1) where a temperature rise of 5.6 ºC was measured.
19. Enthalpy of dissociation (in kJ mol–1) of acetic acid obtained from the Expt. 2 is
(A) 1.0
(B) 10.0
(C) 24.5
(D) 51.4
20. The pH of the solution after Expt. 2 is
(A) 2.8
(B) 4.7
(C) 5.0
(D) 7.0
