Question

When 0.1 mol `MnO_(4)^(2-)` is oxidized, the quantity of electricity required to cmpletely oxidize `MnO_(4)^(2-)` to `MnO_(4)^(-)` is
A. 96500 C
B. `2xx96500C`
C. `9650C`
D. `96.50C`

Answer 1

Correct Answer - C
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
