An aqueoussolutionof NaCI on electrolysisgivesH_(2)(g),CI_(2)(g) and NaOH accordingto reaction 2CI^(-)(Aq)+2H_(2)O rarr 2OH^(-)(Aq)+H_(2)(g)+CI_(2)(g) A direct currentof 25 Awitha current efficiencyof 62% is passed through 20 L of NaCI solution(20%)by weight Howlong will it take to produce 1 kgof CI_(2)

Answer»

`30.20h`
`12.17 h`
`48.71 h`
`14.61 h`

SOLUTION :`(W)/("EQUIVALENT WEIGHT")=("it")/(96500)`
Given `w_(C 12)=10^(3) g` equivalent weight `w_(CI_(2))=35.5` and
`i=(25xx62)/(100) =15.5 A`
HENCE`t=(10^(3)xx93500)/(35.5 xx15.5)=175374.83 s=48.71 h`
