Saad Zahraw Sekhi Sir, I have calculated diffusion layer thickness based on Randles-Sevcik equation only. However the book by Bard and Faulkner "Electrochemical methods" describes the diffusion layer calculation by the following formulae :
diffusion layer = sqrt (2Dt)
Hence, I want to confirm which is the correct method to calculate the diffusion layer.
Moreover, if we are using it in our calculation then what would be the value of ''t''?
