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
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
