The study of Sodium Saccharin (NaSc), this one of the chemical compounds was used as a replacement for natural sugar, which taking by diabetic patients. NaSc was studied by cyclic voltammetric technique to analysis at different temperature using modified glassy carbon electrode (GCE) with carbon nanotubes (CNT) as working electrode (CNT/GCE). Activation energy (Ea*) of NaSc was studied in 1M Na2SO4 as an electrolyte at different temperature using Arrhenius equation at both GCE and CNT/GCE. Other thermodynamic parameters such as activation free energy (∆G*), activation enthalpy (∆H*) and activation entropy (∆S*) were determined at both GCE and CNT/GCE using Eyring equation. Other thermodynamic parameters such as the values of entropy for cathodic current peak of NaSc on GCE and CNT/GCE are positive value, this means that the reaction is spontaneous reversible, but the negative values of entropy is irreversible reaction.
