A quantity of electricity required to reduce 12.3 g of nitrobenzene to aniline arising 50% current efficiency is

Options

  1. A115800 C
  2. B57900 C
  3. C23160 C
  4. D28950 C

Correct answer

A. 115800 C

Step-by-step solution

Molar mass of nitrobenzene = 123 Equivalent mass of nitrobenzene = Molecular mass 6 = 123 6 = 20.5 Number of equivalents of nitrobenzene = Mass Equivalent mass = 12.3 20.5 = 0.6 Amount of charge required = 0.6 × 96500 = 57900 Coulomb Amount of charge required when current efficiency is 50% = 2 × 57900 = 115800 C
