Tardigrade Admin · Accepted Answer

+7MnO4- arrow Mn2+ The reaction can be written as: MnO4- arrow Mn2+ Hence, 5 moles of electrons or 5F of electricity are required for the given reaction.

Q. How many Faradays of electricity are required for the given reaction to occur ?
$M n O_{4}^{-} \to M n^{2 +}$

5 F

3 F

1 F

7 F

$^{+ 7} M n O 4^{-} \to M n^{2 +}$
The reaction can be written as :
$M n O 4^{-} \to M n^{2 +}$
Hence, $5$ moles of electrons or $5 F$ of electricity are required for the given reaction.
