MHT CET 2026 Chemistry question
If standard reduction potential of Zn, Ni and Fe are , and respectively. For the reaction (Stated below) to be spontaneous find out electrodes X and Y considering above electrode potentials
Answer: (D)
Solution
In the given reaction X is oxidised (anode) and is reduced (cathode). A reaction is spontaneous when , i.e. Y must have the higher (less negative) reduction potential. Check each option: (A)
