What is cell entropy change of the following cell?
\( \mathrm{P} \)
\( \mathrm{Pt}(\mathrm{s}) \mid \mathrm{H}_{2} \) (g) \( \mid \mathrm{CH}_{3} \mathrm{COOH}, \mathrm{HCl} \| \mathrm{KCl} \) (aq) \( \mid \mathrm{Hg}_{2} \mathrm{Cl}_{2} \) (s) \( \mid \mathrm{Hg} \) \( \mathrm{P}=1 \mathrm{~atm} \quad 0.1 \mathrm{M} \quad 0.1 \mathrm{M} \)
Emf of the cell is found to be \( 0.045 \mathrm{~V} \) at \( 298 \mathrm{~K} \) and temperature coefficient is
\[
3.4 \times 10^{-4} \mathrm{~V} \mathrm{~K}^{-1}
\]

Given: \( \mathrm{Ka}_{\left(\mathrm{CH}_{3} \mathrm{COOH}\right)}=10^{-5} \mathrm{M} \)
(1) 60
(2) 65.6
(3) 69.2
(4) 63.5
