Time taken to completely decompose 36 g of water by passing 3 A current is

Answer»

`35.8" hr"`
40 hr
`51.8" hr"`
`22.5" hr"`

Solution :`UNDERSET(36g(2 mol))(2H_(2)O) to 4H^(+)+O_(2)+underset((4F))(4e^(-))`
Now `Q=Ixxt` or `t=(Q)/(I)`
`t=4xx((96500" AS"))/((3A)):. 1.C=AS`
`=(128667s)/((3600 s))=35.8 hr`
