QJEEM20Ch7262: JEE Main 2020 Chemistry - Class 12 JEEM20Ch7262 Solution: = +0.34 V = -0.76 V Identify the incorrect statement from the…
= +0.34 V
= -0.76 V
Identify the incorrect statement from the option below for the above cell :
Multiple Choice Options
- A If Eext < 1.1 V, Zn dissolves at anode and Cu deposits at cathode
- B If Eext = 1.1 V, no flow of e– or current occurs
- C If Eext > 1.1 V, e– flows from Cu to Zn
- D If Eext > 1.1 V, Zn dissolves at Zn electrode and Cu deposits at Cu electrode
Step-by-Step Verified Solution
= -
= 0.34 – (–0.76)
= 1.10 V
If Eext < 1.1 V then Zn dissolves at anode and copper deposits at Cathode.
If Eext > 1.1V then Zn deposited at zinc electrodes and Cu deposits at Cu electrode.
= 0.34 – (–0.76)
= 1.10 V
If Eext < 1.1 V then Zn dissolves at anode and copper deposits at Cathode.
If Eext > 1.1V then Zn deposited at zinc electrodes and Cu deposits at Cu electrode.
