# Undergraduate Course: Chemical Engineering Thermodynamics 2 (CHEE08015)

 School School of Engineering College College of Science and Engineering Credit level (Normal year taken) SCQF Level 8 (Year 2 Undergraduate) Availability Available to all students SCQF Credits 10 ECTS Credits 5 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. Course description The following topics will be covered: -Philosophical foundations of Thermodynamics. Intensive/extensive properties. Concept of equilibrium. -Spontaneity in processes and Reversibility. -Introduction of First and second laws. Isentropic processes and isentropic efficiency. -Rankine cycle and power generation. -Refrigeration and Vapour compression cycles. Absorption refrigeration and liquefaction cycles. -Equations of State. Pure components and mixtures -Auxiliary functions: the Gibbs Free Energies. Gibbs FE as a work function and criterion for equilibrium. Maxwell's equations and a sample derivation. -Calculation of change in TD properties between specified states, including calculation of DG. -Phase equilibrium fora single component. Clausius-Clapeyron equation. TD properties of perfect gas mixtures: enthalpy and entropy of mixing. -VLE for ideal mixtures; Raoult's Law. Chemical potential and fugacity, phase rule. -Gibbs FE change for ideal mixtures. -Chemical equilibrium in (ideal) gaseous systems. Standard FE change of reaction. Evaluation of Chemical equilibrium constant at elevated temperatures from Standard data. Calculation of equilibrium composition of a reaction mixture of perfect gases at given T,P.
