`E^(@)` for the cell `Zn(s)|Zn^(2+)(aq)|Cu^(2+)(aq)|Cu(s)` is 1.1V at `25^(@)C` the equilibrium constant for the cell reaction is aboutA. `10^(-37)`B. `10^(37)`C. `10^(73)`D. `10^(73)`

Answer» Correct Answer - B
At 298k,
`E^(@)=(0.0591)/(n)"log"k`
`1.1=(0.0591)/(2)"log"k` (Here n=2)
log `k=(1.1xx2)/(0.0591)=37.22`
`k="antilog" 37.22=1.65xx10^(37)`
