Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Standard Electrode Potential.
The standard electrode potential of the Normal Hydrogen Electrode (NHE) is defined as 0.00 V at 298 K. This is the reference value against which other electrode potentials are measured.
Step 2: Explanation of the options.
- (1) 0.05 V: This is not the value for NHE.
- (2) 0.10 V: This is not the value for NHE.
- (3) 0.50 V: This is not the value for NHE.
- (4) 0.00 V: This is the correct standard electrode potential for NHE.
Step 3: Conclusion.
The correct answer is (4) 0.00 V.
