PPT-Chemical Equilibrium

Dr Ron Rusay Copyright 20032010 RJ Rusay Chemical Equilibrium The reactions considered until now have had reactants react completely to form products These reactions went only in one direction.

Note: the detail in slides marked “ * ” can only be seen if you run the slideshow. Chemistry 6/4/15. What kind of “shifts” did you see yesterday?. In the popular restaurant model, how could you “shift” the number of people in the restaurant?. HW. :. “Direction of shift” for each System completed. Graph of Gradual Evolution. http://anthro.palomar.edu/synthetic/images/graph_of_phyletic_gradualism.gif. Some biologists claim that most evolutionary change takes place as a result of a series of very small changes . Author: Wesley Tung. Technical Things. A chemical equation of a reaction uses mole ratios to describe the production of products from reactants.. In . , hydrogen and oxygen are reactants, and water is a product.. . UNIT-III. . Topics of Chapter:. . Statement and meaning of Phase, component and degree . of freedom.. Derivation of Gibbs phase rule.. Phase equilibrium of one component systems-water, . Back in Time: General gas law . PV=. nRT. <=> P= . nRT. /V. Pressure is directly proportional to number of moles and temperature, and is inversely proportional to the volume occupied by the gas .

Scalar - . a physical quantity that is completely described by a real number. The Meaning of K. . K > 1 . . the equilibrium position is far to the right . K < 1 . . the equilibrium position is far to the left . The value of . K. for a system can be calculated from a known set of equilibrium concentrations. . Chemical System: . A system is described in terms of empirical properties such as . temperature, pressure, volume and amount of substance present.. By definition, all chemical systems are fast, quantitative, stoichiometric and spontaneous! However, this assumption is NOT always true..
