PPT-Unit 3: equilibrium

331 335 Le Châteliers Principle Le Châteliers Principle If a system at equilibrium is subjected to an external stress the equilibrium will shift to  minimize the effects of that stress. Marissa Levy.

Equilibrium of particles. Scalar and Vectors. . Scalar - . a physical quantity that is completely described by a real number. . When the rates of the forward and reverse reactions become equal, the concentrations of the reactants and the products remain constant. This is the stage of chemical equilibrium. This equilibrium is . Read Chapter 13 look at the problems. Do . the AP practice test on page AP-13 A-D. (it is in between numbered pages 547-548). 2. AP Test. Historically, the first question on the free response has ALWAYS been an equilibrium question.. 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.. Duna Jogeswar Rao.
