Which one of the following condition will increase the voltage of the cell represented by the equation?
`Cu(s) + 2Ag ^(+) (aq)` `(Cu^(2+)(aq) + 2Aq(s)`

A

increase in the dimension of Cu electrode

B

increase in the dimension of Ag electrode

C

increase in the concentration of `Cu^(2+)` ion

D

incrase in the concentration of `Ag^(+)` ions

Verified by Experts

The correct Answer is:

D

`E_("cell")=E_("cell")^(@)-(RT)/( nF)"In"(|Cu^(2+)|)/(|Ag^(+)|^(2))`
thus increase in the concentration of `Ag^(+)` ions will increase `E_("cell")`.
