  "term": "Levich equation",
  "field": "Chemistry",
  "definition": "An equation that describes the limiting current at a rotating disc electrode under steady-state conditions, relating it to the electrode rotation rate, the concentration of the electroactive species, and its diffusion coefficient. It is a fundamental equation in electroanalytical chemistry for studying mass transport phenomena. The limiting current is directly proportional to the square root of the rotation rate.",
