What is ilkovic equation and give its significance?

Answer 1

The Ilkovic equation describes the relationship between the current response and the concentration of an electroactive species in voltammetry, particularly in the context of a rotating disk electrode. It is expressed as ( i_d = nFAD^{1/2}C\omega^{1/2} ), where ( i_d ) is the diffusion current, ( n ) is the number of electrons transferred, ( F ) is Faraday's constant, ( A ) is the electrode area, ( D ) is the diffusion coefficient, ( C ) is the concentration of the species, and ( \omega ) is the angular velocity of the electrode. The equation is significant because it allows for the quantitative analysis of reaction kinetics and mass transport phenomena in electrochemical systems, aiding in the understanding of reaction mechanisms and the design of electrochemical sensors.
