The quantity of electricity required to release `112 cm^(3)` of hydrogen
at STP from acidified water is

A

`965C`

B

`1Faraday`

C

`0.1F`

D

`96500C`.

Text Solution

Verified by Experts

The correct Answer is:
A
`2H^(+)+underset(2F)(2e^(-))rarrunderset(22400cm^(3))(H_(2))`
To liberate 22400 `cm^(3)` at STP electricity required =`2xx96500C`
To liberate 112 `cm^(2)` at STP electricity required
`=(2xx96500xx112)/(22400)`
=965C
