Chemical Thermodynamics & Spontaneity Covers calorimeters, the concepts and mathematical application of Hess' Law, enthalpy and entropy, and Gibbs' free energy law. *Electron Configuration An extensive set of notes providing an excellent overview of electron configuration up to the AP level. Great illustrations are provided of each orbital. Lists of questions and exercises are also provided. *Energetics An extensive set of notes providing an excellent overview of chemical thermodynamics up to the AP level. Lists of questions and exercises are also provided. *Enthalpy, Entropy & Free Energy A great overview of all the concepts encountered in thermodynamics. Provides tips, demos, links to websites, articles, exercises and more. *Enthalpy & Gibbs' Free Energy Calculator This calculator can be used to calculate the value of the enthalphy of a reaction or the Gibbs free energy of a reaction. A form provides you with blanks to enter the individual enthalpies or free energy d ata points for a given reaction. Once entered, you simply click on the "Evaluate" button to compute the appropriate value. *Enropy & Gibbs' Free Energy This website is for students who wrestle with the concepts of enthalpy, entropy, how they are different, and how they define if a reaction can be spontaneous under their current conditions. *Gibbs' Free Energy An excellent website that provides a good look at the driving forces behind a reacton and their effect on Gibbs' free energy. Thermochemistry ChemTeam developed this tutorial which covers specific heat, molar heat of vaporization, molar heat of fusion, thermochemistry problems, determining specific heat by experiment, and enthalpy. *The Driving Forces Behind Chemical Change Possibly the most comprehensive source of tutorial aide on chemical thermodynamics you will find on the Web. It includes notes, tutorials, practice problems, and labs.
