For a cell reaction , Cu^(2+) (C_1 , aq) + Zn(s) to Zn^(2+) (C_2 , aq) + Cu(s) of an electro chemical cell , the change in standard free energy , DeltaG^(0) at a given temeprature is

Answer»

`DELTAG^(@)=RT ln.(C_(2))/(C_(1))`
`DeltaG^(@)= - RT ln. (C_(2))/(C_(1))`
`DeltaG^(@) = RT ln C_(2)`
`DeltaG^(@) = - RT ln C_(2)`
