is considered in a state of equilibrium when its properties do not change at time passes. Equilibrium is a state of a reaction where the concentration of all the reactants and all the products remain constant over time. Equilibrium as used in chemical systems means that all the chemical forces in a reaction are in balance and that all physical properties of the system (color‚ density and concentration) of all chemicals species involved remains constant. The equilibrium state can be characterized by

CH 127 – Chem 2 Lab Determination of an Equilibrium constant Goals The purpose of this experiment is to determine the equilibrium constant for the reaction Fe3+(aq) + HSCN(aq) –>FeSCN2+(aq) + H+(aq). The equilibrium constant expression Kc for Reaction is kc=FeSCN2+[H+]Fe3++[HSCN] Procedure *Preparation of the Beer’s law plot Prepare five solutions of FeSCN2+(aq) of known concentrations between 1x10-5M and 1x10-4M by diluting various volumes of 4.62x10-4 HSCN. Calculate the Final concentration

Market Structure Paper August 2‚ 2009 In this paper I will discuss competitive markets‚ monopolies‚ and oligopolies and what role each of these play in an economy? I will also point out: o What the characteristics of each market structure is? o How the price is determined in each market structure in terms of maximizing profits? o How output is determined in each market structure in terms of maximizing profits? o What are the barriers to entry‚ if any? o What role does each market

The First and Second Conditions for Equilibrium The first condition for equilibrium: The second condition for equilibrium: • • ΣF = 0 ΣΓ = 0 • In when both of these conditions are satisfied in static systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from

The movie Equilibrium directed by Kurt Wimmer‚ and the book 1984 written by George Orwell both explore what would happen when a government has complete control. When you let someone think for you and make all of your decisions‚ you lose what makes you human‚ which is your free will‚ and your ability to make conscious decisions. In both the text and movie they take away human identity to gain control. The key differences are the ways Big Brother and Father seize control‚ and what effect it has on

main objective of this experiment was to obtain some experimental measurement of Vapor Liquid Equilibrium for the Ethanol – Water system to verify the literature data. For this the Ethanol – Water system was heated to a certain temperature which is called the equilibrium temperature at atmospheric pressure and equilibrium temperature and compositions of vapor and liquid were measured. At the equilibrium temperature the samples of both vapor and liquid were taken in two different test-tube and the

Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD

offspring have the same genotype ratio as their parents. This example was one of Hardy-Weinberg equilibrium. The next generation will express the same genotype ratio as their parents‚ and so on. But what exactly is needed to create Hardy-Weinberg equilibrium? (Basically‚ a population in Hardy-Weinberg equilibrium s not evolving in any way.) Five specific factors are needed to create Hardy-Weinberg equilibrium within a population- a very large population‚ isolation from other populations‚ no net mutations

Consumer Behavior Segmentation paper When attempting to segment the market for aftermarket truck accessories in the trucking industry we used a combination of lifestyle based segmentation and psychographic based segmentation techniques that we learned in class. Our segments were based on the results of our needs assessment paper which linked the attributes we identified to the benefits and the values. We came up with a rough estimation of the size of each segment by using the information we
