Mon-Day 5
AP: we finished up the Electro unit with some quantitative electrolysis problems. We analyzed the reactions that occur at the anode and cathode for a given electrolysis. We then briefly discussed fuel cells emphasizing that these cells require a continuous supply of reactants which undergo a redox reaction to generate electrical energy/electricity.
Honors: we finished our Le Chatelier problems and introduced the Law of Mass Action and the Law of Chemical Equilibrium. We described how to write the correct equilibrium constant for any given reaction or process: always include aqueous and gaseous reactants and products; NEVER include solid or liquid reactants and products.
Regents: we did several problems in which we wrote the equilibrium constant expression and a couple of problems in which we calculated the value of the Keq by plugging in the equilibrium concentrations of the products and reactants into the equilibrium constant expression.
