NEET Chemistry Standard Electrode Potential MCQ Question
Type: MCQ-numerical-Hard-Class 11
What is the standard cell potential (E° cell) of a galvanic cell constructed using Zn/Zn²⁺ and Cu²⁺/Cu electrodes at 298K?
A
10 V
B
0.34 V
C
36 V
D
0.44 V
Correct Answer
Option A
Detailed Explanation
The standard electrode potential for Zn²⁺/Zn is -0.76 V and for Cu²⁺/Cu is +0.34 V. E° cell = E° cathode - E° anode = 0.34 V - (-0.76 V) = 1.10 V.
