Assume a cell with the following reaction Cu ( s ) + 2 Ag + 1 × 10 - 3 M → Cu 2 + ( 0 . 250 M ) + 2 Ag ( s ) E cell   ∘ = 2 . 97   V E cell   for the above reaction is             V . (Nearest integer) [ Given : log 2 . 5 = 0 . 3979 ,   T = 298   K ]

Correct answer

0

Step-by-step solution

E = E ° - 0 . 059 2 log Cu + 2 Ag + 2 = 2 . 97 - 0 . 059 2 log 0 . 25 10 - 3 2 = 2 . 81   V
