Correct Option - 1
Detailed Solution:

q = 0 as adiabatic process is given

            W = 0 as paxt = 0

            q + W = DU

            q = 0

            W = 0

            Þ DU = 0

CH3COOH + NaOH → CH3COONa + H2O

ΔH = –50.6 kJ/mol

NaOH + SA [HCl] → NaCl + H2O

ΔH = –55.9 kJ/mol

the value of ΔH for ionisation of CH3COOH

⇒ ΔH = +55.9 – 50.6

5.3 kJ/mol
