The standard electromotive force of the cell
\(\mathrm{Fe}\left|\mathrm{Fe}^{2+}(\mathrm{aq})\right|\left|\mathrm{Cd}^{2+}(\mathrm{aq})\right| \mathrm{Cd}\)
If the temperature coefficient of emf is -0.125 V K-1, the values of ΔS° at 25°C would be:
- -20.125 KJ K-1
- -24.125 KJ K-1
- -26.125 KJ K-1
- -22.125 KJ K-1
Answer
(D) -22.125 KJ K -1
