Assertion `(A):` For a Daniell cell `:`
`Zn|Zn^(2+)||Cu^(2+)|Cu` with `E_(cell)=1.1V`, the application of opposite potential greater than `1.1V` results into the flow of electron from cathod to anode. Reason `(R):` Zn is deposited at anode and Cu is dissolved at cathode

Options

A. If both assertion and reason are true, and reason is the true explanation of the assertion
B. if both assertion and reason are true, but reason is not the true explanation of the assertion.
C. if assertion is true, but reason is false.
D. If both assertion and reason are false.

Answer

B

Explanation

Correct Explanation. On applyng external voltage greater than 1.1 V in the daniell cell, the electrons flow in the reverse direction, i.e., from cathode `(Cu^(2+)//Cu)` to anode `(Zn//Zn^(2+))`. The reverse reaction takes place
(i.e., `Zn^(2+)+CutoZn+Cu^(2+)`)
