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

Answer»

increase in the DIMENSION of Cu electrode
increase in the dimension of Ag electrode
increase in the CONCENTRATION of `Cu^(2+)` ion
incrase in the concentration of `Ag^(+)` IONS

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