NEET Chemistry (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a diagram showing the trends in M3+/M2+ standard electrode potentials for 3d transition metals. Which of the following best explains the irregularity in these values?
A
Variation in ionization and sublimation enthalpies.
B
Consistent electron affinity across the series.
C
Uniform atomic radii among transition metals.
D
Constant oxidation state across the series.
Correct Answer
Option A
Detailed Explanation
The irregularity in M3+/M2+ electrode potentials is explained by variations in ionization enthalpies and sublimation enthalpies, particularly for manganese and vanadium.
