Document Content and Description Below
Virtual Lab: Le Chatelier's Principle Inquiry BACKGROUND: Equilibrium exists when the rates of the forward and reverse reactions are equal. When a stress is added to the reaction, the rates are no l ... onger equal. The reaction will proceed in such a way to make the rates back to equal and establish a new equilibrium. This is known as LeChatelier’s principle. PURPOSE: Observe stress on reactions and record the shift that the reaction undergoes to relieve the stress. PRE LAB: 1. Define Equilibrium. - State in which opposing forces are balanced 2. When a system is at equilibrium, are the concentrations equal or constant? - Equal PROCEDURE: For each experiment, click to see the effect of various stressors on equilibrium and record your observations. Then analyze your results and complete the conclusion questions. EXPERIMENT 1: Click to add HCl (increase the H+ concentration) then add NaOH (decrease the H+ concentration) Increasing the H+ concentration shifted the reaction to the ______right_______ Decreasing the H+ concentration shifted the reaction to the ______lef [Show More]
