Summary  This course first introduces the principles and methods of Classical Thermodynamics and the thermodynamic laws in relation to familiar experience; phase change, ideal gas and flow processes; using sources of data such as thermodynamic tables and charts. The concepts of Gibbs free energy and chemical potential are introduced in the context of both phase equilibrium and chemical reaction equilibrium in ideal systems. Power generation and refrigeration cycle are introduced and analysed. Equations of State are also introduced. To enable students to calculate heats of reaction and equilibrium concentrations for gas phase reactions using standard thermodynamic data.

Learning Outcomes
On completion of this course, the student will be able to:
 Understand and apply basic thermodynamic concepts: thermodynamic systems, states, properties, work, heat, energy.
 Represent power generation and refrigeration cycles on TS and PH diagrams and determine the power generation or requirement for a given thermal duty.
 Describe the significance of Chemical Potential in mixtures.
 Use Standard heats and free energies of formation to evaluate equilibrium constants, and hence determine equilibrium concentrations in reacting mixtures at elevated temperatures and pressures.
 Understand deviation between ideal vs. real cycles
