Aim

• The aim with the course is to introduce the classical thermodynamics for the students and also to exercise the students to use the different models presented in the course.

.

Knowledge and understanding
For a passing grade the student must

• Be able to formulate and explain the first and second laws of thermodynamics and be able to calculate energy and entropy changes for temperature, volume and pressure changes.

• Be able to define and explain 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.

• Understand the background to the equilibrium equation for a chemical system

Skills and abilities
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.

• Be able to use phase diagrams for two component systems

• Be able to judge the validity of the models presented.

Judgement and approach
For a passing grade the student must

• Be able to discuss everyday phenomena on the basis of thermodynamical reasoning

• Be able to judge information in the surrounding world (for example in media) on the basis of themrodynamical reasoning.

Contents

• 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.

• Thermodynamics applied to liquid and solid surfaces.
