For the cell reaction,

Zn_{(s)} + 2Ag^{+}_{(aq)} \longrightarrow Zn^{+2}_{(aq)} + 2Ag_{(s)}

Cell potential is less than cell by 0.0592 V at 298 K when

(A) = 1 M and = 0.1 MCorrect
(B) = 1 M and = 0.01 M
(C) = 0.1 M and = 1 M
(D) = 0.01 M and = 1 M

Answer: (A)

Solution

Nernst equation at 298 K with n = 2: . The condition V gives , so
