When 10 ampere current is passed for 80 ...

When 10 ampere current is passed for 80 min., volume of `H_(2)` gas liberated is

A

`4.5 dm^(3)`

B

`5.5 dm^(3)`

C

`5.57 dm^(3)`

D

`6.2 dm^(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
Quantity of electricity =Q=Ampere`xx`Second
`therefore Q=10xx80xx60=48000` Coulomb
`11.2 dm^(3) `of `H_(2)` liberated by 96500 coulomb of electricity. Therefore `x dm^(3)` of `H_(2)` liberated by 4800 coulomb of electricity .
`therefore x=11.2xx4800//96500=5.57`
