`Zn(s) |Z_(n)^(2+)(aq)||Cu^(2+)(aq)|Cu(s)`
Write overall cell reaction and calculate the standard Gibb's energy for the reaction. `[ F 96487 c//mol]`
(b) Mention any two factors which affects the conductivity of electrolytic solution .

Text Solution

Verified by Experts

Data: `E_("cell")^(0)=1.1V, F=96487V`
Cell reaction `Zn(s)+Cu_(aq)^(+) to Zn_(aq)^(2+)+Cu(s)`
n=2
FORMULA: `DeltaG_(0)-n E_("cell")^(0)=-2 xx 1.1 xx 96487`
`DeltaG^(0)=212.27kJ`
