Question

The quantity of electricity required to reduce 12.3g of nitrobenzene to aniline assuming 50% current effcincy is

Answer 1

Hello Dear.

In this reaction , Reaction for reduction
__________________________

C₆H₅NO₂ +6H⁺ +6e⁻ -----→ C₆H₅NH₂ +2H₂O
__________________________


Given in the question :-⇒

Molar mass of nitrobenzene =123

Here 12.3 nitrobenezene Mole= 6×12.3 / 123
= 0.6 
Charge = 0.6 × 96500 
=57900

As 50% efficiency 
So, 2 × 57900
=115800 C .

Therefore the charge required is 115800 C.



I Hope it helps you.
