Lab 4: Le Chatelier’s Principle Name: Cammey Mahowald Lab Partners: None Date of Experiment: March 16‚ 2015 Course: CHE 112 Abstract: The purpose of this experiment is to understand the components of a reaction at chemical equilibrium and use Le Chatelier’s principle to predict the direction an equilibrium position will shift upon changes in the concentration‚ temperature‚ and pressure. It was determined that in the equilibrium of chromate and dichromate it is an exothermic reaction and in the

Experiment 11 Date: 28-3-2011 Title: Interpretation of reaction by the Le Chatelier’s principle Objective: To determine the factors that affecting the equilibrium position Introduction: Le Chatelier’s principle states that if a system in equilibrium is subjected to a change‚ the equilibrium position of the system will shift in a direction to minimize the effect of the change. Iron(III) ions and thiocyanate ions (NCS-) react in solution to produce thiocyanatoiron(III) (FeNCS2+)‚ a

Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application
