which of the following will increase the voltage of the cell with following cell reaction?
`Sn(s)+2Ag^(+)+(aq)rarrSn^(+2)(aq)+2Ag(s)`

Options

A. Increase in the size of the silver rod
B. Increase in the concentration of `Sn^(2+)` ions
C. Increase in the concentration of `Ag^(+)` ions
D. None of the above .

Answer

C

Explanation

`E_("cell") = E_("cell")^(@) - (RT)/(nF) "ln" ([Sn^(2+)])/([Ag^(+)]^(2))` .
