Unformatted text preview: Lecture Notes to CHEM 251 Physical Chemistry for Engineers Winter Semester 2009 Walter Scott wscott@chem.ubc.ca http://www.chem.ubc.ca/personnel/faculty/scotty/index.shtml UBC Chemistry Department 01 Acknowledgements Suzana Straus http://www.chem.ubc.ca/personnel/faculty/straus/index.shtml Keng Chang Chou http://www.chem.ubc.ca/personnel/faculty/chou/index.shtml Keith Mitchell http://www.chem.ubc.ca/personnel/faculty/mitchell/index.shtml These lecture notes were written on an linux system ( http://www.ubuntu.com ) in L A T E X using the seminar , graphicx and animate packages. Diagrams were drawn using the ( http://www.xfig.org/ ) program. Images were manipulated using the GIMP ( http://www.gimp.org ). Function plots and animations were made using the gnuplot program ( http://www.gnuplot.info/ ). Pictures of molecular systems were made using the UCSF Chimera molecular modelling system ( http://www.cgl.ucsf.edu/chimera/ ). 02 Contents 0 Organisational Technicalities 1 Contact Information 2 Electronic Courseware 3 Examination Policy 4 Bibliography 1 Introduction and Overview 1 Micro- & Macroscopic Views of Matter 2 Central Concepts in Thermodynamics 2 Properties of Matter 1 Thermodynamic Systems 2 Equilibrium & Non-equilibrium 3 State Variables & Functions 4 State Functions 5 The Zeroth Law 6 The State of Non-equilibrium Systems 7 The Empirical Gas Laws 8 The Ideal Gas Law 9 The Pressure of an Ideal Gas 10 The Equipartition Theorem 03 11 Daltons Law of Partial Pressures 12 States of Matter 13 The Van der Waals Equation 14 Compressibility Factor 15 Virial Expansion 16 The Law of Corresponding States 17 The Lennard-Jones Interaction Potential 18 Coexistence of Phases and Critical Points 19 The Boltzmann Distribution 20 The Maxwell-Boltzmann Velocity Distribution 21 The Maxwell Speed Distribution 22 Thermosiphons and Heat Pipes 23 Vacuum Distillation 24 Molecular Collisions & Mean Free Path 25 Statistical Thermodynamics Primer 3 The First Law of Thermodynamics 1 Internal Energy, Heat and Work 2 Path Dependence and Independence 3 Enthalpy 4 The First Law in Open Systems 5 Some Applications of the First Law 6 Power and Refrigeration Cycles 7 Thermochemistry: Hesss Law 8 Isothermal Titration Calorimetry 04 4 The Second Law of Thermodynamics 1 Introduction 2 The Carnot Cycle 3 The Second Law 4 Calculating Entropy Changes 5 The Heat Death of the Universe 6 Addendum: Working with the Gaussian Distribution 7 Absolute Entropy and the Third Law 8 Entropy Changes in Chemical Reactions 9 Free Energies 10 The Maxwell Relations 5 Chemical Kinetics 1 Introduction 2 Rate Laws 3 Measuring Reaction Rates & Orders 4 The Arrhenius Equation 5 An Overview of Reaction Types 05 This page intentionally left blank 06 This page intentionally left blank 07 0 Organisational Technicalities...
