STANDARD Chemistry Standard Electrode Potentials MCQ Question
E° values for the half cell reactions are given below: Cu²⁺ + e⁻ → Cu⁺ ; E° = 0.15 V Cu²⁺ + 2e⁻ → Cu ; E° = 0.34 V Which will be the E° of the half-cell ; Cu⁺ + e⁻ → Cu?
+0.49 V
+0.19 V
+0.53 V
+0.30 V
Correct Answer
Detailed Explanation
The E° for the reaction Cu⁺ + e⁻ → Cu can be calculated using the given half-cell reactions. By combining the reactions, we find E° = 0.53 V.
