What happens to the emf for the cell, Zn_ (s) |Zn^ +2 (1M) |Ag^ +1 (1 M)|Ag_ (s) if concentration of Ag^ +1 decreases to 0.1 M?

MHT CET 2025 Chemistry question

What happens to the emf for the cell, \ominus\ Zn_{(s)}|Zn^{+2}(1M)\|Ag^{+1}(1\ M)|Ag_{(s)}\ \oplus if concentration of decreases to 0.1 M?

Answer: (B)

The cell reaction is Zn + 2Ag^+ \rightarrow Zn^{2+} + 2Ag with . Nernst equation: . Initially , so . When : $ = -
