Answer to Question #269366 in General Chemistry for Luffy

Question

When cadmium metal reduces Cu2+ in solution, Cd2+ forms in addition to copper metal. Given that ΔG° = −143 kJ/mol, calculate K at 25°C. What is E°CELL of a voltaic cell that uses this reaction?

Cd(s) + Cu^2+(aq) = Cd^2+(aq) + Cu(s)

Answer 1

Cu²⁺+2e^---->> Cu. E^° = +0.39V

Cd²⁺+2e^-----> Cd E° = -0.14V
