1.	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 cathodeA. If both assertion and reason are correct and reason is correct explanation for assertion.B. If both assertion and reason are correct but reason is not correct explanation for assertion.C. If assertion is correct but reason is incorrect.D. If assertion and reason both are incorrect.
Answer» Correct Answer - B (b) Correct explanation. The cell will work in opposite direction. Cu will be oxidised to `Cu^(2+)` ions. The electrons released will move towards anode and will be taken by `Zn^(2+)` ions to form Zn(s). It will be deposited at the anode.
