How muCHM electricity is required in coulomb for the oxidation of ltbr. `a.` `1 mol of H_(2)O to O_(2)`
`b`. `1 mool ` 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`
