Current necessary to produce hydrogen gas at the rate `1 CC` per second under standard conditions is

Options

A. `8.61 amp`
B. `7.86 amp`
C. `5.55 amp`
D. `9.67 amp`

Answer

A

Explanation

One equivalent of `H_(2)(g)` is liberated by one faraday of electricity, i.e. `11200 C C` (volume of `1` equivalent of `H_(2)(g)` under standard conditions] is produced by `96500` coulombs (amperes per sec). Thus `11200 C C` of `H_(2)(g)` is produced per lselcond by `96,500` amperes or `1 C C` of `H_(2)(g)` is produced per second by
`(96500)/(11200)` amp
or 8.61 amp
