Physical chemistry: equilibrium depends on the imposed constraint
Compare thermodynamics texts and derive ideal-gas conversion at fixed pressure and volume, with dimensionless activities and explicit minimum criteria.
Study route and exercise: University Reading List editorial project.
Who this book is for
For advanced undergraduate readers who have already encountered thermodynamics and want a more systematic chemical treatment. It can also support a graduate refresher. The text is useful when familiar rules about spontaneity and equilibrium need to be connected to carefully defined quantities, constraints and derivatives rather than applied as isolated slogans.
Prerequisites
Previous thermodynamics in physical chemistry, calculus of several variables and confidence with derivatives and differentials. Review state functions and equilibrium before attempting the more formal development.
What it covers
The laws and thermodynamic potentials lead to pure substances, mixtures, reactions, phase equilibria and electrochemical systems. This progression makes the chemical potential and conditions imposed on a system central to interpreting an equilibrium statement. It offers depth beyond an initial engineering energy-balance course.
How to use it
Build a notation sheet and record the independent variables for each potential. Before taking a derivative, state what is held fixed and why that choice matches the physical experiment. Test a relation first on a simple ideal model, then examine the extra information a real mixture requires. Separate a stable-equilibrium criterion from a statement about how fast an actual process occurs.
Edition, preparation and a reading test
The LibreTexts book map provides the online text with chapter attribution and licence notices. This record follows that online work without assigning a print ISBN or year. For reaction equilibrium, keep a sheet of each potential’s independent variables and practise partial derivatives and dimensionless ideal-gas activities. Derive partial pressures from the vessel constraint before forming Q. Fixed T,P and fixed T,V require different minimization statements; knowing K alone does not specify the conversion or the approach rate.
