- The scan rate dependency study helps to determine the nature of the redox reaction thermodynamically whether a particular reaction is reversible, quasi–reversible, or irreversible.
- Changing the scan rate can help differentiate between real electrochemical processes and capacitive currents, particularly when there is double-layer charging or large surface area electrodes are used.
- Also, the resolution of the voltammogram can be increased by varying the scan rate.
Note: A lower scan rate is recommended because a higher scan rate affects the current response and shape of the voltammogram and the diffusion layer size.
