PPT-Equilibrium in the AD/AS Model

Module 19 Learning Objectives The difference between shortrun and longrun macroeconomic equilibrium The causes and effects of demand shocks and supply shocks How to determine if an economy is experiencing a . Rôle. of Prices. MICROECONOMICS. Principles and Analysis. . Frank Cowell. Almost essential . General equilibrium: Basics. Useful, but optional. General Equilibrium: Price Taking. Prerequisites. July 2015. 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 . Dr. Ron Rusay. © Copyright 2003-2010 R.J. Rusay. Chemical Equilibrium. The reactions considered until now have had reactants react completely to form products. These reactions “went” only in one direction.. SCH4U1 . Chapter 7. Equilibrium [noun]. 1. a. :. a state of intellectual or emotional balance . :. . poise. <trying to recover his . equilibrium. > . b. :. a state of adjustment between opposing or divergent influences or . 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 . What’s . New here?. . Incomplete information: . Example: . Battle of the sexes . game,But. Bob . doesn’t know . what Alice wants . (i.e. her payoffs from possible outcomes). In previous examples we had “. When carbon dioxide d_______ in water it forms carbonic acid. The more c______ dioxide the more a_______ the solution becomes . ie. . The pH d_________!. If distilled water (pH 7.0) is exposed to air the carbon dioxide from the air will form dilute carbonic acid (pH 5.5-6.0). Measuring Equilibrium Concentrations. Equilibrium Calculations (ICE Charts). Qualitatively Interpreting the Equilibrium Constant. Meaning of Small Equilibrium Constant. SCH4U – Grade 12 Chemistry, University Preparation. At equilibrium, the number of. people riding up the lift and the. number of people skiing down . the slope . are constant.. Learning Goal . Calculate the equilibrium constant for a reversible reaction given the concentrations of reactants and products at equilibrium.. The height of the top of the block (iceberg, continental crust) would be h. m. ’ + h. c. Response of the crust to a addition of a load (sediment accumulating or a large volcano): the crust “floats” downward to re-establish isostatic equilibrium and the elevation of the crust changes less that the thickness of the material added. . Lecture 8. How do deal with individual ions in aqueous solution?. We can’t simply add Na. . to a solution (positive ions would repel each other).. We can add . NaCl. . How do we partition thermodynamic parameters between Na. . Scalars and vectors. . Types of forces. . Resultant of forces. . 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 .
