Calculate the amount of electricity required in coulombs to convert 0.08 mol of MnO ₄⁻ to Mn ²⁺ .

Options

  1. A96500 C
  2. B38600 C
  3. C48250 C
  4. D19300 C

Correct answer

B. 38600 C

Step-by-step solution

The reaction is MnO ₄⁻+5 e ⁻ Mn ²⁺ For reduction of 1 mole, 5 F electricity is required For 0.08 mole, 0.4 F electricity is required. aligned & 1 ~F =96500 C & 0.4 ~F =96500 0.4=38600 C aligned
