Problem #2. Data are from (Journal of the Electrochemical Society, 164, D159 (2017) Showing fundamental rate constant as a function of supporting electrolyte during SLRR. : k/s-1 CHCIO4/ moldm-³ 0.06 0.03 0.055 0.055 0.045 0.08 0.041 0.11 0.04 0.13 0.03 0.16 0.025 0.22 Studying the material fort this subject assume that reorganization energy is a function of dielectric constant of the electrolyte as: z²e² 12- [1-4] Απέρα where z is the charge of the ion, e is the elementary charge, & is the dielectric constant of the medium which is the function of perchloric acid concentration. The 'a' is the double layer's inner Helmholtz plain separation and so is dielectric constant of vacuum. Try to find in the literature relation for & vs. electrolyte concentration and work you way backwards to find the relation for the value of k vs. electrolyte concentration. Fit your model to the data. Make sure all your assumptions and equations are properly defined. Units as well.
