## Kinetics, Electrochemistry, with Basic Laboratory Course in Physical Chemistry

#### Kinetics

**Basics:** **Formal Kinetics**,
reaction rates and differential equations; integrative and differential
methods, reaction orders; **Reaction laws** for 1^{st} and
2^{nd} order and comparison 0 to 3^{rd} order;
**coupled reactions:** parallel, sequence and back reactions, with
examples from photophysics; **kinetics of complex reactions:**
quasistationary state (Bodenstein principle), chain reactions,
explosions, catalysis, autocatalysis; **temperature dependence**
(Arrhenius and Eyring theories); **further dependences:** pressure,
polarity (Bell-Evans-Polanyi principle), ionicity, substituent effects
(Hammett equation), isotope effects; **applicational aspects:**
photochemical kinetics, biokinetics, oscillating reactions

#### Electrochemistry

**Basics:** electrolytes, ionic
conduction, electrolysis, galvanic element, Faraday´s laws, systems of
units (MKSA vs cgs). **Electrolytic conduction:** (specific)
resistance and (specific) conductivity, molar and equivalent
conductivity. Kohlrausch´s law and limiting equivalent conductivity,
ion mobility, microscopic explanation. Hüttorf transport number.
Hydration of ions. **Electrode potentials**: electrical,
electrochemical, Galvani-, Volta-Potentials, EMF. Nernst´s equations
for metal, redox, gas electrodes. Reference electrodes, NHE, standard
potential, electromotive series. Thermodynamics of EMF. Electrodes of
second kind. **Debye-Hückel theory**: Concept of ionic cloud, charge
distribution and el. potential (Poisson-equ.), Laplacian in polar
coordinates and simplification to central potential. Ansatz for
potential(r) as screened Coulombic potential, determination of radius
for ionic cloud, normalisation. Debye-Onsager equ. for conductivity of
dilute electrolytes. Influence of ac fields. **Activity**: mean
activity coefficient, its concentration dependence. **Weak
electrolytes**: Ostwald´s dilution law, dissociation field effect.
**pH**: concept, buffer. **Diffusion potential:** origin and
calculation, concentration series, elimination of diffusion potential.
**Electrolysis:** Helmholtz double layer, electrode processes:
kathodic and anodic current, Butler-Volmer-equation for the current as
f(electrode polarisation), deviations due to concentration changes or
diffusion. Tafel equ.
