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

PROBLEM SET 3 Problems for Chapter 3 1. Suppose the consumption function in the U.S. is represented by the following equation: C = 200 + .5 YD‚ where YD = Y – T and T = 200. a. What is the level of consumption in this economy if YD = 0? Briefly explain how individuals “pay for” this consumption when YD = 0. b. Given the above parameters‚ calculate the level of consumption if Y = 1200. Suppose Y increases to 1300. What happens to the level of YD as Y increases to 1300 (i.e. calculate

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

temperature before and after mixing was recorded and included in tables. When the experiments were completed analysis was performed using the laws of thermodynamics. The data collected was used in equations to find theoretical values for final equilibrium temperature. The theoretical values were compared with those measured during the experiment. The total average percent difference between the measured final temperature and the theoretical final temperature is less than 5.0%. This low deflection

Chapter 1 Vectors‚ Forces‚ and Equilibrium 1.1 Purpose The purpose of this experiment is to give you a qualitative and quantitative feel for vectors and forces in equilibrium. 1.2 Introduction An object that is not accelerating falls into one of three categories: • The object is static and is subjected to a number of different forces which cancel each other out. • The object is static and is not being subjected to any forces. (This is unlikely since all objects are subject to the force

This paper relates to the concepts I learned from weeks one and two of my Economics class and how market forces affect the price of sugar. Characterized by volatile prices and widespread intervention sugar is one of the most massively traded agricultural commodities in the international and local markets (Sariannidis‚ 2010‚ p. 1). Sugar is one of the staple foods most people cannot live without. The reason I am using sugar as the subject of this paper is because I observed raw sugar has doubled its

Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration

Abstract Equilibrium is the condition of a system in which competing influences are balanced. In the experiment we measured and experimented for the equilibrant force‚ conditions and center of gravity. Our results showed consideration as to disregarding other forces than weight and tension. 1. Introduction Equilibrium is a state of balance in which it is a condition where there is no change in the state of motion of a body. Equilibrium may be observed on objects which are at rest and also

com/articles/2008/06/06/business/air.php The Principle of Market Equilibrium The equilibrium price is the price at which the quantity demanded of a good or service is equal to the quantity supplied. The Principle of Market Equilibrium states that perfectly competitive markets are always moving toward said equilibrium. If the price is too high or low‚ there will be a surplus or shortage‚ respectively‚ which will drive the price towards the “market-clearing” equilibrium price. When there is a shift of the demand and/or

For a manager is a business setting it is important for them to understand how market equilibrium is maintained. Simple economic principles such as supply and demand are crucial in the business world when it comes to everything‚ especially making very important day to day decisions. The Process The intersection of the supply curve and the demand curve is considered market equilibrium and the price point (investopedia‚ 2012). This is another way of saying that the economic forces are balanced
