Endothermic Reaction Solid barium hydroxide octahydrate (Ba(OH)2*8H2O) and ammonium thiocyanate (NH4SCN) are mixed in a beaker, which is then placed on a few drops of water on a small board. The reaction that occurs is highly endothermic.
Thermodynamics : CompareEntropyQual (16 Variations) Indicate which substance in each of the following pairs of substances you expect to have higher entropy. Assume that you have a mole of each substance and all substances are at the same temperature.
Using Graphs of Gibbs Energy versus Temperature in General Chemistry Discussions of Phase Changes and Colligative PropertiesRobert M. Hanson, Patrick Riley, Jeff Schwinefus, and Paul J. Fischer The use of qualitative graphs of Gibbs energy versus temperature is described in the context of chemical demonstrations involving phase changes and colligative properties at the general chemistry level. Hanson, Robert M.; Riley, Patrick; Schwinefus, Jeff; Fischer, Paul J. J. Chem. Educ.2008, 85, 1142.

Does the Addition of Inert Gases at Constant Volume and Temperature Affect Chemical Equilibrium?João C. M. Paiva, Jorge Gonçalves, and Susana Fonseca This article examines three approaches, leading to different conclusions, for answering the question "Does the addition of inert gases at constant volume and temperature modify the state of equilibrium?" Paiva, João C. M.; Gonçalves, Jorge; Fonseca, Susana. J. Chem. Educ.2008, 85, 1133.
John Krenos Metiu has created a significant set of volumes on undergraduate physical chemistry. The integration of Mathematica and Mathcad workbooks into the four texts provides instructors with an attractive new option in teaching. Krenos, John. J. Chem. Educ.2008, 85, 206.

Disorder (GCMP)David M. Whisnant Disorder: this is a resource in the collection "General Chemistry Multimedia Problems". A spontaneous change is one that has a natural tendency to occur without needing to be driven by an external influence. This problem will explore the influence of entropy, a measure of disorder, on the spontaneity of a few processes. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.

Two Solids (GCMP)David M. Whisnant Two Solids: this is a resource in the collection "General Chemistry Multimedia Problems". When two solids barium hydroxide octahydrate, Ba(OH)2. 8H2O and ammonium thiocyanate, NH4SCN are mixed, they react. We will explore the thermodynamics of the reaction. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
