Module Overview

This module addresses the essential concepts of chemical thermodynamics that are required by chemical engineers.  Starting from fundamentals, it builds up to prediction of equilibrium states for complex reacting mixtures, and vapour-liquid systems that exhibit non-ideal behaviour.  This will give students an appreciation of what lies beneath chemical engineering flowsheeting and design software packages




Completion of the progress requirements of Level HE1

Module Aims

To provide a solid foundation in Chemical Thermodynamics that will enable interpretation and prediction of a range of chemical and physical transformations such as phase changes and chemical reactions.  This knowledge will underpin and support the associated subjects of reaction engineering and separation processes





Learning Outcomes




Upon successful completion of the module you will be able to:


·                Recognise the principles whereby process flow-sheeting programmes use chemical thermodynamics to model equilibrium conditions in various unit operations


·                Demonstrate a sound understanding of the procedures necessary to deduce chemical and phase equilibria from readily available physical property data and state equations, and understand the conventional symbols, reference states and standard conditions used.


·                Confidently estimate chemical and phase equilibria for ideal and non-ideal systems of moderate complexity over a range of temperatures and pressures and estimate the energy changes involved in changes of chemical composition and physical state.


·                Accurately evaluate mixture compositions for the various equilibrium systems considered.
