The cell, Zn | Zn ²⁺(1 M ) | Cu ²⁺(1 M ) | Cu ( E _ cell ^0=1.10 ~V ) , was allowed to be completely discharged at 298~K . The relative concentration of Zn ²⁺ to Cu ²⁺ [ [ Zn ²⁺ ] [ Cu ²⁺ ] ] is

Step-by-step solution

aligned & E _ cell = E _ cell ^ - 0.0591 n Q & Where Q = [ Zn ²⁺ ] [ Cu ²⁺ ] aligned For complete discharge E _ cell =0 So E _ cell ^ = 0.591 2 [ Zn ²⁺ ] [ Cu ²⁺ ] | [ Zn ²⁺ ] [ Cu ²⁺ ] |=10^ 37.3 Hence, (C) is correct.
