  2. Outline • Kinetic • Overpotential Hydrogen • Kinetic Overpotential Hydrogen • Reference

  3. Kinetic Kinetic (Kinetika) membahas tentang laju reaksi dan mekanisme terjadinya reaksi

  4. Overpotential Hydrogen Adanya gerakan ion (kinetik) yang lambat menyebabkan potensial yang menyimpang dari nilai Nernst Pada Hydrogen : 2H+ + 2e- = H2

  5. Kinetic Overpotential Hydrogen • Mass Transfer-Controlled Reaction-Concentration Overpotential

  6. Kinetic Overpotential Hydrogen • Interfacial Reaction Rate Control-Activation Overpotential

  7. Kinetic Overpotential Hydrogen

  8. Kinetic Overpotential Hydrogen • Difusi H3O+dariBulk Solution menujudouble layer • H3O+melewatiDouble Layer • Dehidrasi ion H3O+ H2O + e • a) Electrochemical H3O+ + M + e- M-H + H2O (pelepasan ion) b) Pembentukanmolekul-molekulHydrogen 2 M-H  2M + H2

  9. Kinetic Overpotential Hydrogen • Desorpsi gas H2 darielektroda • Difusi gas H2keluar/menjauhielektroda
