Question

A quantity of electrcity required to reduce 12.3 g of nitrobenzene to aniline arising 50% current efficiency 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.
