How many coulombs of electricity are required for the oxidation of one mol of water to dioxygen ?

A

`1.93 xx10^(4)`C

B

`19.3 xx10^(5)`C

C

`9.65 xx10^(4)`C

D

`1.93 xx10^(5)`C

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(2)Orarr2H^(+)+(1)/(2)O_(2)+underset(2F)(2e^(-))`
Hence columbs of electricity required for the oxidation of one mole of water to dioxygen
`=2xx96500=193000C=1.93xx10^(5)C`
