When 10A currentis passed for 80 min,the volume of hydrogen gas liberated is

Answer»

11.14L
5.57L
22.4L
2.78L

Solution :`H^(+) to underset(1F)(E^(-)) to (1)/(2)H_(2)`
At STP ,
`:'` 96500 C LIBERATES =11.2`H_(2)`
`:. 10xx80xx60C` will liberate `=(11.2xx10xx80xx60)/(96500)LH_(2)`
=`5.57L` hydrogen gas
