Chapter 25, Problem 25.11QAP

Interpretation Introduction

Interpretation:

Scan rate at experiment 2 should be calculated.

Concept introduction:

The peak current can be represented as follows:

$i_p=2.686\times {10}^5{\text{ n}}^{3/2}{\text{ A c D}}^{1/2}{\text{ v}}^{1/2}$

Here,

I_p = peak current

n = number of electrons transferred in the redox event

A = electrode surface area

C = concentration

D = diffusion coefficient

V = scan rate
