What is the Levich equation?
The Levich equation is a mathematical model used to predict the current observed at a rotating disk electrode (RDE). It is a tool used in electrochemical research and is named after Veniamin Grigorievich Levich, who first developed the RDE.
Why does it matter?
The Levich equation is crucial in understanding the behavior of electrochemical reactions at the surface of the RDE. It helps researchers and scientists to predict the current observed at the electrode, which is essential in various applications, including electrochemical synthesis, corrosion, and electrochemical sensors.
