← ScienceWhich consequence results when insufficient positive charge causes an increase of the Debye length within an electrochemical system at constant temperature?
A)Faster reaction rates at electrodes
B)Reduced double-layer capacitance✓
C)Increased electrolyte polarization
D)Enhanced ionic conductivity in solution
💡 Explanation
A longer Debye length results from reduced electrostatic screening, because the electrical double layer expands proportional to the Debye length parameter; therefore capacitance decreases, rather than increasing, because charge separation grows with separation distance maintaining equal voltage.
