1. The problem statement, all variables and given/known data In the electrochemists technique of cyclic voltammetry, the peak current, I, is a simple function of the scan rate, v, according to the Randles-Sevcik equation: 2. Relevant equations I = 0.4463nFAc(nF / RT)^1/2 D^1/2 V^1/2 Where n is the number of electrons transferred, F is the Faraday constant, D is the diffusion coefficient, and C the concentration of analyte. Write an expression to describe the gradient of a graph of I (as "y") against v (as "x") ie. dI/dV 3. The attempt at a solution As a chemist, my maths isn't particularly strong, but I tried to answer the problem as best as possible. I treated the equation posted above as I = k*v^1/2, where k is treated as a constant and the answer I got was dI/dV = 1 ÷ 2*√v (assuming that constants when differentiated become zero). I would be delighted if a member could show me a thorough step by step procedure on how the answer should actually look if I'm incorrect in my logic. I appreciate your time and concern, Kindest Regards, Luke.
