← ScienceWhich outcome reduces the reaction rate within an electrochemical cell?
A)Increased electrode surface film resistance✓
B)Higher operating temperatures utilization
C)Increased concentration of reactive species
D)Strong electric double layer generation
💡 Explanation
Increased resistance from surface films lowers rate because *electron tunneling* requires overcoming the barrier. This results in slower kinetics; therefore, resistance decreases the rate, rather than increasing it, due to higher temperatures promoting kinetics.
