Poly (Methyl Methacrylate) (PMMA) was studied as a chemical compound used almost universally for teeth base manufacture. The study was focused on the effect of different temperatures of potassium ferricyanide K 3 [Fe(CN) 6 ] in 1M KCl as an electrolyte using CV technique at modified glassy carbon electrode (GCE ) with poly-acrylonitrile (PAN) and PMMA as working electrode (PAN/PMMA/GCE). The thermodynamic functions such as activated enthalpy (ΔH*), free energy (ΔG*) and entropy (ΔS*) for redox current peaks of K 3 [Fe(CN) 6 ] in 1M KCl on (PAN/PMMA/GCE) electrodes, using Eyring was explored. The determination of the activation energy (Ea*) determined by Arrhenius equations for the oxidation-reduction current peaks of K 3 [Fe(CN) 6 ] to compare values obtained by K 3 [Fe(CN) 6 ] in 1M KCl on various electrodes was studied.
