Calculate the quantity of electricity that would be required to reduce 12.3 gm of nitrobenzene to aniline if current efficiency is 50%

A

347400 coulomb

B

115800 coulomb

C

23160 coulomb

D

694800 coulomb

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(6)H_(5)NO_(2) + 6H^(+) + 6e^(-) rarr C_(6)H_(5)NH_(2) + 2H_(2)O`
moles of `C_(6)H_(5)NO_(2)= 0.1`, Eq of `C_(6)H_(5)NO_(3)= 0.6`
no. of Faradays = 0.6, Current efficiency = 0.5
So actual no of Faraday = 1.2
