You can see the equations in Page 200 of the attached file.

For example, if the reaction is diffusion-controlled, and then perform Cyclic voltammetry at various scan rates. Using Randles−Sevcik equation and then electrode surface area can be examined!

Hello Sumit Meshram ,

Run the CV. Obtain the values of peak current (I), scanrate (v) and plug in all the other parameters (concentartion of bulk solution C, number of electrons involved inredox reaction n, diffusion coefficient of molecule in solution,D) in Randles-Sevick equation to find the area (A).

Dr Gudipati Neeraja Sinha, can we get all the value of other parameters (concentration of bulk solution C, number of electrons involved in redox reaction n, diffusion coefficient of molecule in solution,D) from CV value? Or we actually need to know in advance those parameters value?

Thank you and have a nice day!

Regards.

Dear Nurfarhana nabila Mohd Noor ,

1) Concentration of bulk solution C, is the cocentration of analyte you are using to record CV.

2) Number of electrons involved in redox reaction n, and diffusion coefficient of molecule in solution,D can be obtained from literature.

3) Values of peak current (I), scanrate (v) are obtained from CV.

Plugging 1,2 and 3 in Randles sevick equation, you can calculate electroactive surface area,A.

Thank you

Dear Dr. Gudipati Neeraja Sinha, thanks a lot for your assistance.

Regards.
