Question

Calculate amount of electricity required to reduce the 6.5 gram of nitro benzene to aniline

Answer 1

.

In this reaction , Reaction for reduction

__________________________

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

__________________________

Given in the question :-⇒

Molar mass of nitrobenzene =123

Here nitrobenezene Mole= 6×6.5 / 123

= 0.3

Charge = 0.3 × 96500 

= 28950

As 50% efficiency 

So, 2 × 28950

=57900 C .

Therefore the charge required is 57900C.
