What Information Can Be Derived from a Tafel Plot?
From a Tafel plot, one can derive:
- Tafel Slope (b): Indicates the rate-determining step of the reaction. A smaller slope suggests a more efficient catalyst. - Exchange Current Density (j₀): Represents the intrinsic activity of the catalyst. A higher j₀ indicates a more active catalyst. - Reaction Mechanism: The slope can give clues about the reaction mechanism and the number of electrons involved in the rate-determining step.
