Learning Goal: Develop problem-solving skills wing chemical equilibria and oplying Le Chatter's principle Solving problems with chemical equilibrium If you know the basic principles of chemical equilibrium, you can analyze and predict reversible reactions. To analyze any reversible reaction, follow these problem-solving steps: 1. Identify the reactants and products for the given chemical reaction. 2. Draw a diagram of the reaction to better understand what is happening 3. Identify how increasing or decreasing a product or reactant stresses the equilibrium...
Experiment: Equilibrium and LeChatelier's principle 1. Read and familiarize yourself with the lab. Writing a "recipe" to follow might be a good way to do this. You'll finish lab faster as well. Do not go overboard with this recipe business, it is just a way to remember what you read and digest it better than usual. 2. Read and familiarize yourself with the equilibrium Chapter of your textbook. For prelab, hand in this sheet with the answer to what's below:...
Q(1) During a chemical reaction, what defines when the concentrations of the reactants and products reach a constant level? A) Elementary process B) Rate constant C) Reversible reaction D) Equilibrium E) Rate law Q(2) Which is the correct equilibrium constant expression for the following reaction? FeO(s) + H2(g) - Fe(s) + H2O(g) A) Ke = [H2O] / [H2] B) Ke=[Fe][H2O] / [Fe2O3] [H2] C) Ke=[Fe) (H20] / [Fe2O3] D) Kc = [Hz] / [H2O] E) Ke= [Fe2O3] [H2] / [Fe][H2O]...
