3. Two molecules, A and B, with concentrations of 1.00 mM are studied at a glassy carbon electrode at 100 mV/sec. Each species undergoes a one-electron reduction. The diffusion coefficient for A is 64.2 x 10-“ cm²/s, while B has a diffusion coefficient of 4.16 x 10-6 cm²/s. Briefly explain how the peak height of the reduction wave will differ between molecules A and B.
