A variable, opposite external potential (E_(ext)) is applied to the cell Zn| zn^(2+)(1M) || Cu^(2+)(1M)| Cu , of potential 1.1 V. When E_(ext) lt 1.1V and E_(ext) gt 1.1 V , respectively electrons flow from:

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

The standard cell potential for the cell is , Zn|Zn^(2+)(1M)||Cu^(2+)(1M)|Cu [E^@ for Zn^(2+)//Zn=-0.76V, E^@ for Cu^(2+)//Cu=+0.34V]

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.
