How many faradays of electricity is required for the following processes ?

Options

A. Reduction of 1 mole `Fe^(3+)` to Fe
B. Reduction of 1 mole `Fe^(3+)` to `Fe^(2+)`
C. Oxidation of 1 `g Sn^(+2)` to `Sn^(+4)`
D. Oxidation of 1 `gH_(2)O` to `O_(2)`

Explanation

(a) `Fe^(3+)+3e^(-) to Fe`
`2,89,500C`
(b) `Fe^(3+)+e^(-) to Fe^(2+)`
`96,500C`
(c ) `Sn^(+2) toSn^(+4)+2e^(-)`
1626 C
(d) `H_(2)O to (1)/(2)O_(2)+H_(2)`
`O^(2-)to(1)/(2)O_(2)+2e^(-)`
`12,062.5C`
(e ) `Cl^(-) to (1)/(2)Cl_(2)+e^(+)`
`2718.3 C`
