Given`:`
Oxidation`H_(2)O_(2) rarr O_(2)+2H^(o+)+2e^(-)" "E^(c-)=-0.69V,`
`2F^(c-)rarr F_(2)+2e^(-)" "E^(c-)=-287V,`
Reduction `: H_(2)O_(2)+2H^(o+)+2e^(-) rarr 2H_(2)O" "E^(c-)=1.77V,`
2I^(c-)rarr I_(2)+2e^(-)" "E^(c-)=-0.54V,`
Which of the following statements is `//` are correct ?

Options

A. `H_(2)O_(2)` behaves as an oxidant for `I_(2)//I^(c-)`
B. `H_(2)O_(2)` behaves as an reductant for `I_(2)//I^(c-)`
C. `I^(c-)//I_(2)` behaves as an reductant for `H_(2)O_(2)`
D. None of these is correct

Answer

a,c

Explanation

Anode `:2I^(c-)rarrI_(2)+2e^(-)+2e^(-),E_(a(o x i d))^(2c-)=-0.535impliesE_(a(Red))^(c-)=+0.535V`
Cathode`:H_(2)O_(2)+2H^(o+)+2e^(-)rarr 2H_(2)O,`
`E^(c-)._(cell)=(E^(c-)._(cell)-E^(c-)._(a))_(R)=1.77-0.53=+ve`
Note that `:`
Anode`:H_(2)O_(2) rarr O_(2)+2H^(o+)+2e^(-),`
`E^(c_._(a(o x i d))=-0.69V`
Cathode`:I_(2)+2e^(-)rarr 2I, " "E^(c-).c_(red))=+0.535V`
E^(c-)._(a(red))=+0.69V`
`E^(c-)=E^(c-)._(cell)-E^(c-)._(a)=0.535-0.69=-ve`
