    Chemical Equilibrium: Le Châtelier’s Principle   Abstract This experiment entitled "Chemical Equilibrium" aims to help students to investigate the effects of concentration and temperature upon the position of equilibrium in a cobalt chloride solution‚ Co(H2O)62+. In this experiment‚ cobalt crystal is dissolved with distilled water and ethanol which the initial colour is purple-pinkish and a few drops of concentration of HCl is added to the test tube‚ the final colour is in deep blue colour. Upon

    Le Chatelier’s principle and chemical equilibrium systems Jan Samuel Matuba‚ Mark Cel Gonzaga Chemical Engineering Department‚ College of Engineering‚ University of the Philippines‚ Diliman 1100 ------------------------------------------------- January 11‚ 2012 DISCUSSION Reaction rates determine the speed at which products are formed from the reactants. Expressed as concentration divided by time‚ reaction rates measure the rate of disappearance of the reactants‚ and‚ conversely‚ the rate

    Le Châtelier’s principle states that The system will have one reaction dominate until the offsetting changes allow the rates of the forward and reverse reactions to be equal again (reestablishing equilibrium). If the forward reaction dominates in order to offset the changes‚ we say the system “shifts to the right” or “shifts toward products” in order to reestablish equilibrium conditions. This will increase the concentration of the products and decrease the concentration of the reactants. However

    Applications of Le Châtelier’s Principle (September 11 - 15‚ 2014) **The purpose of this experiment was to visually observe the effects of how changing certain aspects of the reaction affected the observed equilibrium. PROCEDURE: Introductory activity Part A: Effect of Concentration: Two different temperature water baths were created‚ one at 65-70oC‚ the other ice‚ and set aside for Part B. 20 mL of potassium thiocyanate solution were poured into a petri dish. The initial color and all subsequent

    Chemical Equilibrium: Le Chatelier Principle By Sarah Ramos and Kristina Todorovic Chemistry 203 DEN Dr. Mohamed El-Maazawi Part A. Acid-Base Indicators Purpose In this part of the experiment‚ we will find a reagent that will shift the acid-base equilibrium reaction described by Equation (2) in one direction and then a second reagent that will cause the equilibrium position to shift back in the opposite direction. Introduction An acid–base indicator

    Experiment No. 2: Dynamic Equilibrium and Le Chatelier’s Principle December 1‚ 2011 Final Formal Results Le Chatelier’s Principle states that “when a stress is applied to a chemical system at equilibrium‚ the equilibrium shifts in a direction that reduces the effect of stress” (Gross‚ Abenojar‚ and Tan 23). Moreover‚ it helps us “predict the direction of the shift of the equilibrium” (Silberberg 745). Silberberg also stated that there are three kinds of disturbances - concentration‚

    observe an equilibrium reaction counteracting changes to it’s system all in accordance to Le Chatelier’s principle. An equilibrium reaction can be pushed toward products or reactant based on changes in temperature or concentration. The reversibility of reaction will also be looked at. Pre-Lab questions 1. The concentrations of products and concentrations of reactants remain constant but both reactions are still going on‚ just at the same rate. 2. Le Chatelier’s principle when an equilibrium
