The EMF of the cell: \( \mathrm{Ag}, \mathrm{AgCl} \) in \( 0.1 \mathrm{M}-\mathrm{KCl} \| \) satd. \( \mathrm{NH}_{4} \mathrm{NO}_{3} \| 0.1 \mathrm{M}-\mathrm{AgNO}_{3} \), \( \mathrm{Ag} \) is \( 0.42 \mathrm{~V} \) at \( 25^{\circ} \mathrm{C} .0 .1 \mathrm{M}-\mathrm{KCl} \) is \( 50 \% \) dissociated and \( 0.1 \mathrm{M}- \) \( \mathrm{AgNO}_{3} \) is \( 40 \% \) dissociated. The solubility product of \( \mathrm{AgCl} \) is (2.303 \( R T / F=0.06) \)
(a) \( 1.0 \times 10^{-10} \)
(b) \( 2.0 \times 10^{-9} \)
(c) \( 1.0 \times 10^{-9} \)
(d) \( 2.0 \times 10^{-10} \)
