temperature‚ concentration‚ and pressure on equilibrium Introduction Our ongoing discussion has been on systems at dynamic equilibrium: for a reversible reaction‚ the rate of the forward reaction is equal to the rate of the reverse reaction. What happens if equilibrium is disturbed? In this lab activity‚ we are going to examine the effect of changing reaction conditions on the position of equilibrium. Part I: Effect of temperature We will consider the equilibrium system [Co(H2O)]2+(aq) +

Security Dilemma the Collective Action Problem and the Nash Equilibrium. Criticism of the United Nations highlight the lack of power it has and its reliance on superpowers for legitimacy. The use by states of the UN is conditional on whether it serves state self-interest and whether the value of participating outweighs the cost (Abbott and Snidal 2005: 27). This brings into question why states would allow the UN to impose International laws and Norms that erode state sovereignty and how this

LAB REPORT 4 DETERMINING AN EQUILIBRIUM CONSTANT CAUSION 1. Potassium thiocyanate (KSCN) is hazardous 2. Wear protective material before performing the experiment. INTRODUCTION This experiment outlines the techniques necessary to determine the equilibrium constant for the formation of an iron(III) thiocyanate complex ion (FeSCN2+) from Fe3+ and SCN- . The quantitative preparation of several solutions and subsequent measurement of the solution absorbance

In this experiment‚ equilibrium will be examines in the reaction beteween the iron (III) ion and the thiocyanate ion: Fe3+ (aq) + SCN- (aq) ------ FeSCN2+ (aq) The FeSCN2+ complex ion has a blood red color while the iron and the thiocyanate ion are colorless. Therefore‚ the shift in the reaction can followed by noting a change in the intensity of the clood red color‚ which indicates a change in the concentration of the complex ion FeSCN2+. If the reaction shifts to the right‚ the blood red color

this model‚ a …nancial crisis caused by systemic defaults can shift the economy from an equilibrium with positive borrowing/lending to an equilibrium with no borrowing/lending. In this no-lending equilibrium‚ neither traditional …scal or monetary policy tools are e¤ective in increasing output. Fiscal and monetary policy can only increase the likelihood of the equilibrium evolving to a borrowing/lending equilibrium. 1 Introduction The fundamental economic activities are production and transportation

and sellers and competition as a process of rivalry that may or may not terminate in an end-state. In the end-state conception of equilibrium‚ the focus of attention is on the nature of the equilibrium state in which the contest between transacting agents is finally resolved; if there is recognition of change at all‚ it is change in the sense of a new stationary equilibrium of

three types of competition: depending on whether firms compete on the basis of their prices only‚ waiting time standards only‚ or on the basis of prices and waiting time standards. We establish in each of the three competition models that a Nash equilibrium exists under minor conditions regarding the demand volumes. We systematically compare the equilibria with those achieved when the firms service each market segment with a dedicated service process. Key words: marketing; competitive strategy; noncooperative
