When 0.1   m o l   M n O 4 2 - is oxidized the quantity of electricity required to completely M n O 4 2 - to M n O 4 - is

Options

  1. A96500 C
  2. B2 × 96500 C
  3. C9650 C
  4. D96.50 C

Correct answer

C. 9650 C

Step-by-step solution

M n O 4 2 - → M n O 4 - 0.1 mole v . f . = 1 So, 0.1 m o l e = 96500 × 0.1 = 9650 C charge is required
