The energy conversion involved in a galvanic cell is

For the reduction of silver ions with copper metal,the standard cell potential was found to be $+ 0.46 \ V$ at $25^oC.$ The value of standard Gibb's energy,$\Delta G^o$ will be .......... $kJ.$
$(F = 96500 \ C \ mol^{-1})$

When an acid cell is charged,then

When a lead storage battery is charged,it acts as a:

Give the cell reaction and symbolic representation of the galvanic cell obtained by $E^o_{Ni^{2+}|Ni} = -0.23 \ V$ and $E^o_{Ag^{+}|Ag} = 0.80 \ V$.

Select the incorrect option,when a lead storage battery is discharged $-$
