A Daniell cell `:`
`Zn|Zn^(2+)||Cu^(2+)|Cu` with `E_(cell)=1.1V` is given. Is this a spontaneous cell?

Text Solution

Verified by Experts

The correct Answer is:
b
Both `(A)` and `(R)` are correct but `(R)` is not the correct explanation of `(A)`. Refer Figure.
Correct explanation `:` On applying external voltage greater than `1.1V` in a Daniell cell, the current flows in the reverse direction `i.e.,` from `Zn` to `Cu(` cathode to anode `)` and electrons flow from `Cu` to `Zn` .
`Zn` is deposited at `Zn` electrode and `Cu` dissolves at `Cu` electrode. The reaction is `:`
`Zn^(2+)+Cu rarr Zn+Cu^(2+)`
