.Equilibrium constants for ideal gases.
The aim of the first part of this course is ,starting from the energy-levels of atoms and molecules, obtained through Quantum Mechanics/Quantum Chemistry, to give insight into their fundamental role in the interpretation of atomic and molecular (rotational, vibrational, electronic)spectra.This part thereby gives further theoretical support to the course on structure determination in 3BA.
The second part shows how these same energy-levels give access, in a statistical-mechanical context ,via the partition function, to the classical thermodynamical state functions (energy,free energy, entropy..)and how finally equilibrium constants of chemical reactions can be evaluated.In this sense a link is drawn to the course on Thermodynamics in 2BA.
The final grade is composed based on the following categories:
