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.
