Calculate the maximum possible electrical work that can be obtined from the cell under the standard conditions at 298 K Zn|Zn^(2+)(aq)||Ni^(2+)(aq)|Ni(s) Given E_(Zn^(2+))^(@)(aq)|Zn(s)=-0.76" V ", E_(Ni^(2+))^(@)(aq)|Ni(s)=-0.25" V "

Answer»


SOLUTION :`E_(cell)^(@)=E_((CATHODE))^(@)-E_((anode))^(@)=[(-0.25)-(-0.76)]=0.51" V"`
n=2,F=96500" C"`
DeltaG^(@)=-nFE_(cell)^(@)=(-2)xx(96500C)xx(0.51" V")=-98430" CV"=-98430" J"=-98.430" kJ"`.
