At STP 1.12 litre of `H_(2)` is obtained on flowing a current for 965
seconds in a solution . The value of current is

A

10

B

1

C

1.5

D

2

Text Solution

Verified by Experts

The correct Answer is:
A
`2H^(+)+underset(2"mole"2xx96500C)(2e^(-))rarrunderset("1mole"22.4"lt")(H_(2)`
To liberate 22.5 lt of `H_(2)` gas, electricity required
`=2xx96500C`
To liberate 1.12 lt of `H_(2)` gas, electricity required
`=(2xx96500xx1.12)/(965"sec")=1 0` ampere
