When 0.1 mol MnO_(4)^(2-) is oxidized, the quantity of electricity required to cmpletely oxidize MnO_(4)^(2-) to MnO_(4)^(-) is

Answer»

96500 C
`2xx96500C`
`9650C`
`96.50C`

Solution :The OXIDATION REACTION is
`MnO_(4)^(2-)toMnO_(4)^(-)+e^(-)`
1 mol of `MnO_(4)^(2-)` for oxidation requires electricity=1F=96500C
`therefore0.1` mol of `MnO_(4)^(2-)` will REQUIRE electricity =9650C
