There values of E_(0) of some reactions are given {:(I_(2),+,2e^(-),rarr,2I^(-),E_(0)=0.54"volts"),(Sn^(+4),+,2e^(-),rarr,SN^(2+),E_(0)=0.152"volts"),(Cl_(2),+,2e^(-),rarr,2Cl^(-),E_(0)=1.36"volts"),(Fe^(+3),+,e^(-) ,rarr,Fe^(2+),E_(0)=0.76"volts"),(Ce^(+4),+,e^(-),rarr,Ce^(3+),E_(0)=1.6 "volts"):} Hence

Answer»

`Fe^(3+)` oxidizes`Ce^(+3)`
`Ce^(4+` can OXIDIZE `Fe^(2+)`
`Sn^(2+)` will REDUCE `Fe^(3+)` to `Fe^(2+)`
`Cl_(2)` will be liberated from KCI by passing `I_(2)`.
