PPT-Equilibrium and change

The story of Krakatoa August 27 1983 The island was destroyed along with every living thing in its lush forests The remaining part of the island was buried in over 40 m of volcanic ash Within 9 months life returned to the island. 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.. 3.3.1- 3.3.5 Le . Châtelier's. Principle. Le . Châtelier's. Principle. If a system at equilibrium is subjected to an external stress, the equilibrium will shift to . minimize the effects of that stress.. CMPT 882. Computational Game Theory. Simon Fraser University. Spring 2010. Instructor: Oliver Schulte. 1. Equilibrium Refinements. A complex game may have many Nash . equilibria. .. Can we predict which one players will choose?. 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 . 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). A . reversible reaction . can be approached from either direction. In a . closed system. , no reactants or products can enter or escape. For equilibrium to be achieved, a reaction must be . reversible. SSEMI2c, 3b: . Explain. and illustrate the effects of price floors and ceilings. . The intersection of supply and demand. Equilibrium Price. Where Demand and Supply Meet. Equilibrium is the point where Demand and Supply cross. . 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, . 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.. This web quiz may appear as two pages on tablets and laptops..

Resultant of forces. . Equilibrium of particles. Scalar and Vectors. . 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. .
