MHT CET 2023 Chemistry question

Calculate the for \mathrm{Zn_{(s)}\,|\,Zn^{++}_{(1M)}\,||\,Cd^{++}_{(1M)}\,|\,Cd_{(s)}} at C [V; V]

(A)0.36 VCorrect
(B)1.17 V
(C)-0.36 V
(D)-1.17 V

Answer: (A)

Solution

In the cell notation the left electrode is the anode (oxidation, Zn) and the right electrode is the cathode (reduction, Cd). V. The cell reaction is $\mathrm{Zn
