Some standard electrode potentials at 298 K are given below: (2021-Shift-2)
Pb²⁺/Pb \(\text { ⇒ }\) –0.13 V
Ni²⁺/Ni \(\text { ⇒ }\) –0.24 V
Cd²⁺/Cd \(\text { ⇒ }\) –0.40 V
Fe²⁺/Fe \(\text { ⇒ }\) –0.44 V
To a solution containing 0.001 M of X²⁺ and 0.1 M of Y²⁺, the metal rods X and Y are inserted (at 298 K) and connected by a conducting wire. This resulted in dissolution of X. The correct combination(s) of X and Y, respectively, is (are)
(Given: Gas constant, R = 8.314 J K^–1 mol^–1, Faraday constant, F = 96500 C mol^–1)
