Learning outcomes
Knowledge and understanding
For a passing grade the student must
- know the first and second laws of thermodynamics and be able to
calculate energy and entropy changes for temperature, volume and
pressure changes.
- know the definitions of free energy and chemical potential and
be able to use them for equilibrium calculations.
- know the thermodynamics of simple mixtures-mainly ideal
solutions, but also simple models for nonideal systems. Be able to
use activities and activity cofficients.
- be able to predict different colligative properties of a
solution, such as osmotic pressure, freezing point depression and
boiling point elevation, from the knowledge of the composition of
the studied system.
- be able to use phase diagrams for two component systems
- understand the background to the equilibrium equation for a
chemical system.
- be able to use different methods to measure surface
tension.
- charactarize different types of surfactants.
- know what a micell is and the meaning of the critical micell
concentration, cmc.
- know the meaning of: a liquid crystal , flotation, adsorption
isotherms and colloidal stability.
Competences and skills
For a passing grade the student must
- be able to calculate pressure, volume and temperature in ideal
and nonideal gases.
- be able to determine the temperature and pressure dependence of
the different phase equilibria in a one component system.
- be able to calculate the vapour pressur and boling point of a
two component solution.
- be able to calculate the temperature and pressure dependence of
equilibrium constants.
- be able to use a numerical calculator to solve equations and
integrate and also to use the calculator in least square fits of
experimental data to a polynom function.
Judgement and approach
For a passing grade the student must
- understand the validity of the models presented in the
course.
Contents
The course treats two main areas are:
Thermodynamics:
Basic concepts of thermodynamics such as work and heat, entropy,
enthalpy, free energy and chemical potential.
Equations of state for gases.
Calculations on reversible, irreversible and adiabatic
processes.
Quantitative treatment of phase equilibrium in systems of one
component.
Quantitative calculations of the relations between pressure,
temperature and composition in non-ideal systems of two components
with one or more phases. This includes concepts such as partial
molar quantities and activity, calculations of colligative
properties and a thermodynamic description of distillation.
Thermodynamic treatment of chemical equilibrium.
Surface chemistry:
The interfaces between a liquid phase and a gas. The surface
tension and different experimental methodes to determine the
surface tension of a solution. Gibbs adsorption isotherm. Kelvin
equation.
Surfactants. Micelles; methodes to determine the critical
micellar concentration (cmc). Liquid crystalline phases.
Solubilisation.
Solid surfaces. Adsorption and wetting
Charged surfaces; the DLVO-theory.
