How many coulombs are required for the reduction of 1 mol of `MnO_(4)^(-)` to `Mn^(2+)` ?

A

`96500C`

B

`1.93xx10^(5)C`

C

`4.83xx10^(5)C`

D

`9.65xx10^(6)C`.

Text Solution

Verified by Experts

The correct Answer is:
C
`MnO_(4)^(-)+8H^(+) +5e^(-)rarrMn^(2+)+4H_(2)O`
1 mole 5 mole( 5F)
Electricity required `=5xx96500C=482500C`
` =4.825xx10^(5)C`
