Calculate cell potential at 298K for the following cell. Zn_((S))|Zn^(2+)(0.6M)||Cu^(2+)(0.3M)|Cu_((S))[E_(cell)^(Theta)=1.1V]

Answer»

SOLUTION :Reaction : `Zn_((S))|Zn^(2+)(0.6M)||CU^(2+)(0.3M)|Cu_((S))`
Where, `n=2,""E_(cell)^(THETA)=1.1V`
`[Zn^(2+)]=0.6,""[Cu^(2+)]=0.3M`
Cell potential=`E_(cell)`
`E_(cell)=E_(cell)^(Theta)-(0.059)/(n)"log"([Zn^(2+)])/([Cu^(2+)])`
`=1.1-(0.059)/(2)"log"(0.6)/(0.3)`
`=1.1-0.0295log2`
`=1.1-(0.0295)(0.3010)`
`=1.1-0.0089`
`=1.0911`V
