 HA + OH- → H2O + A- + q1 kJ
H+ + OH- → H2O + q2 kJ
The enthalpy of dissociation of HA is
  • a)
     (q1+ q2)
  • b)
     (q1 - q2 ) 
  • c)
     (q2 - q1)
  • d)
    - (q1+ q2)
Correct answer is option 'C'. Can you explain this answer?

HA + OH- →H2O + A- + q1kJH++ OH- →H2O + q2kJThe enthalpy of ...
HA + OH⁻ → H₂O + A⁻ + q1…..(1)
 H₂O + q2 → H ⁺ + OH⁻…..(2)
Adding eqn 1 and 2,
HA + q2 → H⁺ + A⁻  + q1
hence , bond dissociation energy of HA is (q2 - q1)
