Equilibrium and Acid Base Test Review: May 2012 Things to know: 1. Explain DYNAMIC EQUILIBRIUM. Why does a reaction at equilibrium look like it is NOT reacting? 2. Are all reactions equilibrium reactions? What assumptions do we make when we say that a reaction does NOT take place or that it is UNIDIRECTIONAL and goes 100% to completion 3. Be able to sketch a graph of the following (assuming that you start with all reactants and no products) : a. A reaction that really doesn’t do anything

temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring how much KMnO4 was needed to help Na2C2O4 reach chemical equilibrium at certain temperatures. In doing this‚ we will have fulfilled all the goals of our experiment‚ as well as being able to determine the Solubility of Na2C2O3 at both 20 and 100 C‚ in addition to determining both experimental and theoretical ∆H

Ashley Silva Lab 7: Three Stooges in Chemical Reactions Objective: The purpose of this lab is to experimentally determine the equilibrium constant‚ Kc ‚ for the following chemical reaction: Fe3+ (aq) + SCN-(aq) ↔FeSCN2+(aq) Background Information: A system is at equilibrium when the rate of the forward reaction is the same as the rate of the reverse reaction. There is no change in concentration for the reactants or products at chemical equilibrium. When the system is disturbed there

Chemical Equilibrium: Finding equilibrium constant‚ Kc 1 Abstract Chemical reactions are accompanied with formation of products. A reaction can be reversible or forward according to the rate of formation of product. However‚ they do not reach completion and the mixture remains in equilibrium. This theory help us the study the existence of equilibrium constant‚ Kc. This constant is temperature dependent‚ and it must be calculated at given temperature. This equilibrium constant

Arjun Pahwa Math Research Paper The Application of the Nash Equilibrium in Game Theory to Microeconomics ! One of the most challenging problems a business owner comes across is the amount of a certain item he or she should stock and the price at which to sell it. Many factors play into finding this appropriate price. These include the cost of stocking the item‚ the projected demand‚ and what the competition is pricing the same item at. The latter of the three factors is considered to be the most

TITLE Vapour Liquid Equilibrium OBJECTIVE To find the Vapour-Liquid Equilibrium (VLE) relationship for binary mixture and to plot the equilibrium curve. INTRODUCTION The term equilibrium is referred to as when a system is in a static condition and there is absolutely no changes that occur as time goes by. Vapour-liquid equilibrium is a condition where a liquid and its vapor are in equilibrium with each other‚ a condition or state where the rate of evaporation is equal to the rate of condensation

SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT OF A REACTION UNIVERSITY OF THE PHILIPPINES‚ DILIMAN QUEZON CITY‚ PHILIPPINES August 2‚ 2013 ABSTRACT The objective of this experiment is to determine the equilibrium constant‚ denoted Keq‚ for the formation of [Fe(SCN)]2+ complex which is a product of the reaction between the ions Fe3+ and SCN-. In performing this experiment‚ solutions containing FeCl3 and KSCN‚ diluted in HCl‚ were measured for their absorbance using a UV-Vis

Determination of the Equilibrium Constant for Ferric Thiocyanate In this laboratory exercise‚ the equilibrium constant(Kc) for the reaction between the Ferric Ion (Fe3+) and the Thiocyanate Ion (SCN-) was determined. After measuring the absorbance of the Ferric Thiocyanate‚ and carrying out some calculations; it was determined that Kc=130.81M Introduction: Chemical equilibrium is established when a reaction exists in a state where the forward reaction rate is equal to its reverse reaction
