How many hours does it take to reduce 3 moles of `Fe^(3+)` to `Fe^(2+)` with 2A current intensity ?

Text Solution

Verified by Experts

Given, Current = 2.0 ampere,
`3Fe^(3+)+3e^(-)rarr3Fe^(2+)`
Charge required = 3 Faraday
= `3xx96500` coulomb
= 289500 coulomb
We know, Charge = Current `xx` Time
or Time = `(289500)/(2)`
= 144750 sec = 40.20 hrs.
