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.. Types of Separation. Mechanical Means of Separation. Density Separation. Centrifugation. Non-Mechanical Means of Separation. Chromatography. Distillation. Froth Flotation. 2.3 Separating the Substances in a Mixture. SMILE 2016 Winter Teacher’s Workshop. ChemE. Student Background. Presenting my Senior Project at the OSU Engineering Expo, Spring 2015. 5. th. year student in Chemical Engineering. How I chose to be a . Intended Student Learning. Must be able to describe the dynamic nature of a chemical system at equilibrium. Must be able to write . K. c. expressions that correspond to given reaction equations. Perform calculations involving . 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.. 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 . Energy, Rates, and Equilibrium.

Hamden, CT. Lecture Presentation. The Concept of Equilibrium. . Chemical equilibrium. occurs when a reaction and its reverse reaction proceed at the same rate. In the figure above, equilibrium is finally reached in the third picture.. The Haber process proceeds as follows:. . 2NH. 3 (g). + 92KJ ↔ N. 2 (g). + 3H. 2 (g) . . If the equilibrium concentrations are:. [NH. 3. ] = 3.1x10. -2. M. [N. 2. ] = 8.5x10. -1. M. [H. 2. Pathways to Improve Economic Considerations in Fuel Cycle Transition. Brent Dixon.

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. .
