A galvanic cell consists of one half-cell that contains Ag( s ) and Ag + ( aq ),

Question

A galvanic cell consists of one half-cell that contains Ag(s) and Ag+(aq), and one half-cell that contains Zn(s) and Zn 2+(aq). What species are produced at the electrodes under standard conditions?
Ag+(aq) + e- Ag(s) E° = +0.80 V
Zn 2+(aq) + 2 e- Zn(s) E° = -0.76 V

A galvanic cell consists of one half-cell that contains Ag(s) and Ag+(aq), and one half-cell that contains Zn(s) and Zn 2+(aq). What species are produced at the electrodes under standard conditions?
Ag+(aq) + e- Ag(s) E° = +0.80 V
Zn 2+(aq) + 2 e- Zn(s) E° = -0.76 V

Ag(aq) is formed at the cathode and, Zn(s) is formed at the anode. Ag(s) is formed at the cathode, and Zn 2+(aq) is formed at the anode. Zn(s) is formed at the cathode, and Ag+(aq) is formed at the anode. Zn 2+(aq) is formed at the cathode, and Cu(s) is formed at the anode.

Explanation / Answer

the one with greater Eo value will be cathode
so at cathode,
Ag+ changes to Ag

at anode,
Zn changes to Zn2+

Answer:
Ag(s) is formed at the cathode, and Zn 2+(aq) is formed at the anode.
