3 1 0 4
UNIT I ELECTRICAL DOUBLE LAYER 9
Thermodynamics of ideally polarizable and non-polarizable interfaces- Lipman equationdetermination
of interfacial tension, charge density, surface excess and double layer
capacitance by electro capillary & bridge methods- Helmholtz, Gouy-Chapman and stern
models of the double layer with discussion of potential and charge distribution inside the
double layer-contact adsorption and its determination.
UNIT II ELECTRODE KINETICS 9
Concepts of equilibrium potential, Nernst equation, overpotential and its different types,
equilibrium exchange current density-derivation of Butler-Volmer equation –high field and
low field approximations – charge transfer resistance and polarizability of the interface –
concepts of rate determining step, Stoichiometric number, reaction order – Determination of
kinetics parameters [ io, ks, ()] by Tafel and linear polarization methods.
UNIT III ELECTROCATALYSIS 9
Chemical catalysis and electro catalysis – comparison of electrocatalysts – electro catalysis
in simple redox reactions involving adsorbed species – electronic and geometric factors in
electrocatalysts -Discussion on the mechanisms of hydrogen evolution and oxygen
reduction reactions.
UNIT IV ELECTROCHEMICAL TECHNIQUES I 9
Ion selective electrodes – Principles of potentiometry and amperometry- determination of
dissolved oxygen. Linear sweep voltammetry and cyclic voltammetry derivation of Randles-
Sevciks equation – effect of sweep rate-analysis of cyclic voltammograms.

equation for a planar and spherical electrode- significance of spherical diffusion – derivation
of Ilkovic equation.- Chronopotentiometry and analysis of chronopotentiograms-derivation
of sands equation for constant current input under linear diffusion- concepts of Faradaic
impedance –derivation of kinetic parameters from impedance measurements – Nyquist and
bode plots for simple redox reactions-principles of scanning probe techniques-STM-AFM
and SECM.
