For the cell, Zn_ (s) |Zn^ +2 (1M)||Ag^ + (1M)|Ag_ (s) If concentration of Zn^ +2 decreases to 0.1 M at 298 K, then emf of cell

MHT CET 2025 Chemistry question

For the cell, \ominus\ \mathrm{Zn_{(s)}|Zn^{+2}(1M)||Ag^{+}(1M)|Ag_{(s)}}\ \oplus If concentration of decreases to 0.1 M at 298 K, then emf of cell

Answer: (C)

Cell reaction: \mathrm{Zn + 2Ag^+ \to Zn^{2+} + 2Ag}, . Nernst equation at 298 K: . Initially (1 M, 1 M): , so . When M and M: $ =
