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

Options

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

Answer

D

Explanation

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