Chemistry Journal 7.06 Equilibrium Driving Question: How do the reaction rate and concentration of the reactants and products in a chemical reaction affect equilibrium? How do you recognize dynamic equilibrium in chemical reactions? In a closed system, reactions reach dynamic equilibrium when … Answer These Questions from the video: · What are spontaneous reactions? · How do engineers get reactions to move in the non-spontaneous direction? · What does the video mean when it describes reactions as moving dynamically at the same time? How do forward and reverse reactions reach dynamic equilibrium? Describe what happens to the concentrations of NO2 to N2O4 During the forward and reverse reactions in the interactive. · slide 1 · Slide 2 · Slide 3 · Slide 4 · Slide 5 What does a double arrow in a chemical reaction mean? Do reactions stop when they reach equilibrium? Why or why not? What are two misconcpetions about chemical equilibrium? · misconcpetion 1 · misconception 2 How can physical changes lead to dynamic equilibrium? From the video- Give an example of how chemical equilibrium is used in our world How can you predict the position of equilibrium for a chemical reaction? What is the formula and variables of the equilibrium constant? *The specific ______________________ position reached by a system depends on the initial concentration of each substance What does the value of K tell us about the equilibrium position? · If K is close to one? · If K is greater than one? · If K is less than one? How can graphs represent the dynamic equilibrium of a chemical reaction? Example of Rates of Reaction Graph: the reaction has reached equilibirum when the rate of forward and reverse reactions is Equal/Constant (circle only one). Example of concentration Graph: the reaction has reached equilibirum when the concentration of reactants and Products is Equal/Constant (circle only one).
