This course serves as an introduction to chemical kinetics, statistical thermodynamics, quantum chemistry, spectroscopy and molecular modeling. It offers a detailed understanding of chemical phenomena in terms of the structure and dynamics of the molecules involved.

You will first learn the basic principles of chemical equilibrium and chemical kinetics, thus you will gain the ability to approach chemical reactions from a molecular point of view. Then, you will learn the underlying principles of quantum mechanics, how they can be applied to a number of model systems and how the spectra of the molecules are governed by the quantum mechanical properties of molecules. And, finally you will develop the ability to model molecules and chemical reactions, to formulate all the thermodynamic and kinetic parameters in terms of the properties of the atoms and molecules that make up macroscopic chemical systems.

### Chemical Thermodynamics - Background Infomation

Thermodynamics deals with the relations between the energies and the properties of the systems at equilibrium. The zeroth law of thermodynamics defines the temperature of a system, the first law, the energy; and the second law the entropy.

### Chemical Equilibrium (Week 1-3)

The properties of chemical potential, thermodynamic properties of mixtures, chemical equilibrium in a mixture of ideal gases, the equilibrium constants, the temperature dependence of the equilibrium constant-van’t Hoff equation, the LeChatelier principle.

### Chemical Kinetics (Week 4-6)

Reaction rate, effect of temperature, Arrhenius equation, effect of concentration, rate laws, order of a reaction, first-order and second-order reactions, steady state approximation, complex reactions, opposing, parallel and consecutive reactions.

### Kinetic Theories (Week 7)

The activation energy, unimolecular reactions – Lindemann mechanism, the collision theory, the transition state theory.

### Quantum Chemistry (Week 8-12)

The structure of matter, electromagnetic radiation, blackbody radiation, the photoelectric effect, atomic spectra, Bohr’s model of the atom, DeBroglie’s principle, classical wave equation, Schrodinger equation, the postulates of quantum mechanics, the quantum mechanics of some model systems-the free particle, particle in a box, the harmonic oscillator, the rigid rotator, the Hydrogen atom, approximation methods and multielectron atoms, molecular structure and covalent bond, Huckel molecular orbital theory, π-approximation, reaction indices, molecular spectroscopy.

### Structure and Thermodynamic Properties (Week 13-14)

The energy of a system, the entropy of a system, partition functions, molecular motions-translational, rotational and vibrational motions, calculation of molecular properties, calculation of kinetic parameters.
