NEET Chemistry Galvanic Cells MCQ Question
What is the standard cell potential (emf) of a galvanic cell constructed with the following half-cells: Cu²⁺/Cu with a reduction potential of 0.34 V and Zn²⁺/Zn with a reduction potential of -0.76 V?
10 V
0.42 V
-1.10 V
0.76 V
Correct Answer
Detailed Explanation
The cell potential is calculated by subtracting the anode potential from the cathode potential: E°cell = 0.34 V - (-0.76 V) = 1.10 V.
