NEET Chemistry Galvanic Cells MCQ Question

Type: MCQ-numerical-Easy-Class 12

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?

A

10 V

B

0.42 V

C

-1.10 V

D

0.76 V

Correct Answer

Option A

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.
