Which outcome is driven by increased entropy during water electrolysis?

A)Gaseous product mixing improvement
B)Reduced activation energy barrier
C)Increased overpotential requirement overall
D)Suppressed bubble concentration at electrodes

💡 Explanation

Electrolysis generates separate H₂ and O₂ gases. Gas mixing spontaneously increases entropy via diffusion; therefore, gaseous product mixing improvement occurs rather than a decrease to organized phases, because increased randomness dominates the system thermodynamics.
