• Resumen

  • Students determine kinetic and thermodynamic parameters of different metal�solution interfaces. These parameters are obtained from potentiostatic curves using the Tafel and the Arrhenius equations. The work involves the variation of type of metal, solution concentration, and temperature. The results allow the discussion of the polarizability, transfer coefficient, and activation energy of the processes, as well as the differences between them.
