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

For thousands of years‚ humans relied on their intuition to understand how the world works. Sure‚ the approach may have led to a few mistakes along the way -- it turns out the Earth isn’t flat‚ for instance -- but ultimately it worked fairly well. Slowly but surely‚ humanity gained an understanding of everything from the laws of motion to thermodynamics‚ and all of it made intuitive sense. And then quantum mechanics came‚ the absolutely baffling branch of physics exploring the very smallest types

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

Usually the power of the present societies is tripartite. The power is divided into an executive‚ a legislative and a judicative part. As though is it also in the science fiction film Equilibrium written and directed by Kurt Wimmer. After World War III only one civilised stronghold is left‚ the city-state Libria. The city-state contains the same structure of state as we know it today from totalitarian states. However the power of state is tripartite and Preston is part of the executive apparatus

Equilibrium Essay How does Equilibrium fulfil the conventions of a dystopic text? In what way does it subvert them? 1000-1500 words. A dystopia is a futuristic and technologically advanced oppressive world with an overbearing totalitarian government who maintain strict authoritarian control over its population. Dystopia’s are often concealed as utopias since everybody appears to be equal and life appears to be fair‚ but in reality freedom is greatly restricted under a dystopia. Kurt Wimmer’s Equilibrium

Kino’s imaginary story indicated that equilibrium is not only necessary at the lowers of social status‚ but also required in the economy and global market today. Jamie Woodwell‚ in her article about mortgage banking‚ titled‚ A Detour to Dis-Equilibrium‚ speaks about the global market saying‚ “When a shock hits a market— a dramatic shift in supply or demand— the market moves to dis-equilibrium. When that happens buyers and sellers cannot come to terms‚ the market slows and little new business is transacted”
