Question

quantity of electricity required to reduce 1 mol nitrobenzene to aniline​

Answer 1

123 g of nitrobenzene use 6 moles electron for complete reduction. Therefore the amount of charge required = 57900 x 2 = 115800 C.

Answer 2

Explanation:

Reaction for reduction :

C6H5NO2+6H++6e−⟶C6H5NH2+2H2O

Given, molar mass of C6H5NO2=123

Here, 12.3 g nitrobenzene mole =1236×12.3=0.6

Charge =0.6×96500 coloumbs

             =57900

Efficiency =50%

⇒  2×57900= coloumbs

∴  charge required is 115800 coloumbs.
