PPT-Equilibrium Calculations

Law of chemical equilibrium For an equilibrium a A b B c C d D K C c D d A a B b K is the equilibrium constant for that reaction The mean concentration in molarity. photochromism. of O. 4. +. in argon matrices. Ryan M. Ludwig and . David . T. Moore. Chemistry Department, Lehigh University. 69. th. ISMS, Univ. Illinois Urbana-Champaign. June 17, 2014. Cryogenic spectroscopy . Reactions are reversible. A + B C + D ( forward). C + D A + B (reverse). Initially there is only A and B so only the forward reaction is possible. As C and D build up, the reverse reaction speeds up while the forward reaction slows down.. AP . Chem. Mr. Nelson. The Concept of Equilibrium. The term . reversible reaction . is used to describe reactions that can go in either the forward or the reverse direction. Equilibrium. is used to specify that a reversible reaction has reached an .

Condition which the concentrations of all reactants and products in a closed system cease to change with time. Occurs when opposing reactions are proceeding at equal rates.

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. .
