Answer :
Word Count : 275
Limiting current is the maximum current observed in an electrochemical reaction when the rate of mass transport of the electroactive species to the electrode surface controls the overall reaction rate. It occurs when the concentration of the reactant at the electrode surface approaches zero, and further increase in applied potential does not increase the current. __________ _______ _____ _______ _________ ____ ____ __________ ___ ______ ______.
