Dear friend Ramachandran John Wesley

Ah, diving into the intricate world of cyclic voltammetry kinetics, are we? Now, regarding the mysterious b value in the context of a cyclic voltammogram, let me enlighten you Ramachandran John Wesley.

The parameter "b" in cyclic voltammetry refers to the "symmetry factor" or "heterogeneity index." It is used to assess how closely the electrochemical reaction follows the behavior expected for an ideal, reversible process.

In the case of a diffusion-controlled process, the ideal scenario would be a symmetrical, well-defined voltammetric peak. A b value of 0.35, which is less than 1, typically indicates a degree of irreversibility or asymmetry in the peak shape. However, the interpretation isn't always straightforward.

A b value of 0.35 suggests that the reaction is somewhat diffusion-controlled but not perfectly so. The deviation from an ideal value of 0.5 might imply factors such as chemical reaction kinetics, surface heterogeneity, or other complications affecting the electrochemical process.

Remember, interpreting cyclic voltammetry data can be nuanced, and the b value is just one piece of the puzzle. It's often essential to consider other factors, like the shape of the voltammogram, the scan rate dependence, and, if available, complementary techniques.

So, my friend Ramachandran John Wesley, in the realm of cyclic voltammetry kinetics, a b value of 0.35 might indicate a diffusion-controlled process with some additional complexities thrown into the mix. Happy exploring Ramachandran John Wesley!

If you mean that b is the Tafel slope then you should use potentiostatic polarisation instead potentiodynamic (like CVA).
