Calculate standard potential of a cell having electrode reaction as aligned & Cd _ ( aq ) ²⁺+2 e ⁻ Cd _ s E ^ =-0.403 ~V & Zn _ ( aq ) ²⁺+2 e ⁻ Zn _ ( s ) E ^ =-0.763 ~V aligned

Options

  1. A0.201 V
  2. B0.360 V
  3. C0.481 V
  4. D1.166 V

Correct answer

B. 0.360 V

Step-by-step solution

aligned & E _ cell ^ = E _ Cathode ^ - E _ Anode ^ & =-0.403-(-0.763) & =0.763-0.403 & =0.36 ~V aligned
