How much electricity is required in coulomb for the oxidation of :
(a) `1` mol of `H_(2)O` to `O_(2)`,
(b) `1` mole of `FeO` to `Fe_(2)O_(3)` ?

Options

A. 1 F
B. 2 F
C. 4 F
D. `0.5` F

Answer

A

Explanation

`underset(+2)(FeO) to underset(+3)(Fe_(2))O_(3)` i.e., `Fe^(2+) to Fe^(3+) + e^(-)`
i.e., 1 mole of FeO requires 1 F .
