Expert Answer:

Given:
 
Mass of nitrobenzene = 12.3 gm
 
Current efficieny = 50%
 
Potetial V = 3 V
 
Energy = ?
 
Reduction reaction is,
 
C6H5NO2 +6H+ + e → C6H5NH2 + 2H2O
 
Moles of C6H5NO2 to be reduced 
 
equals fraction numerator 12.3 over denominator 123 end fraction

space equals 0.1 space mol
 
 
According to the equation, 0.1 mole of C6H5NO2 will require 0.6 mole of electrons. But efficiecy of current is 50%.
Therefore, 0.1 mole of C6H5NO2 will require 1.2 mole of electrons.
 
Electricity carried by 1.2 mol of electrons = 1.2 × 96500 
 
                                                            = 115800 C
