Consider the following E ° values: E ° L i + | L i = - 3.05 V , E ° C u 2 + | C u = + 0.34 V Under similar conditions, the potential for the reaction C u + 2 L i + → C u 2 + + 2 L i , is

Options

  1. A- 3.39 V
  2. B+ 3.39 V
  3. C- 2.69 V
  4. D+ 2.69 V

Correct answer

A. - 3.39 V

Step-by-step solution

E Cell o = E red o Cathode − E red o Anode Given E ° L i + | L i = - 3.05 V , E ° C u 2 + | C u = + 0.34 V For the reaction, C u + 2 L i + → C u 2 + + 2 L i , E ° = - 3.05 + - 0.34 = - 3.39 V
