How much electricity is required I coulomb for the oxidation of
(i) 1 mol of `H_(2)O` to `O_(2)`?
(ii). 1 mol of `FeO` to `Fe_(2)O_(3)`?

Answer

`a. 193000C`,`b.96500C`

Explanation

`a.` `H_(2)O rarr 2H^(o+)+(1)/(2) O_(2)+2e^(-)`
`1 mol H_(2)O=2F=2xx96500C`
`b.` `FeO rarr (1)/(2)Fe_(2)O_(3)`
`Fe^(2+) rarr Fe^(3+)+e^(-)` ,
`1 mol FeO=1F=96500C`
