CHEM313 Equilibrium Chemical Thermodynamics
Chemical Sciences

Course summary

Pre-requisite: A pass in higher secondary and working knowledge in basic calculus 

Course Outline and Objective: By its origin, thermodynamics is closely related to the study of heat engines and thermodynamic processes. However, the science of thermodynamics should also be understood as the study of thermodynamic properties of substances. In this course, the point of view according to which thermodynamics is concerned with the study of macroscopic properties obtained from macroscopic laws. Students undergoing this course will be equipped to evaluate various thermochemical properties from different experimental variables. From solving problems, students may realise the connection between thermodynamics with biological systems and natural processes. 

Unit I: Behaviour of gases and liquids: Real gases, virial equation of state, gas liquid phases - molecular structure of liquids 

Unit II First and second laws: First law of thermodynamics, Internal energy, work and heat, enthalpy, effect of enthalpy with temperature, thermochemistry – state functions and exact differentials – Joule Thomson effect – adiabatic changes – Entropy: definitions, Carnot cycle, Clausius inequality, entropy changes in physical processes, measurement of entropy - Third law: Nernst theorem and third law entropy  

Unit III System properties and consequences: Helmholtz and Gibbs energies, spontaneous process, maximum work, Standard Gibbs energies – Maxwell relations, temperature, pressure effects on internal, Helmholtz, Gibbs energies, fugacity 

Unit IV Physical transformations: Phase stability and phase diagrams, phase rule, thermodynamics of phase transitions – simple mixtures: Partial molar quantities, thermodynamics of mixing, ideal solutions, ideal dilute solutions, excess functions, colligative properties – Phase diagrams: non reacting and reacting binary systems, azeotropes, eutectics, ternary systems 

Unit V Equilibrium systems: Activities – solute activity, mean activity coefficients, Debye-Huckel limiting law and theory, activity coefficient – Gibbs energy minimum and equilibrium: effect of temperature and pressure on Gibbs energy change and equilibrium constant Ionic equilibrium: Half-cell reactions and electrodes, types of cells, liquid junction potential, Nernst equation, thermodynamics of cells, determination of standard potentials, activity coefficients, equilibrium constants
