CHEM 110 Recitation 15 Recitation 15 Learning Objectives Know what is meant by equilibrium. Be able to give some examples of phase equilibria Describe chemical equilibrium (give an example). What is the Law of Mass action? Write the equilibrium constant expression for a gas phase reaction What is the difference between K p and K c ? Know the quantitative relationship between K p and K c. Be able to calculate K p given K c and the reverse. What is heterogeneous equilibria? Be able to write the expression for the equilibrium constant for heterogeneous equilibria. Given the value of an equilibrium constant for a reaction, know what the equilibrium mixture will look like (mostly products or reactants?). Given the value of the equilibrium constant for a reaction, be able to calculate the value of the equilibrium constant for reactions that are reversed, doubled etc.

Unformatted text preview: Know what is meant by reaction quotient (Q), What is the difference between Q and K eq ? Use Q to predict the direction of a reaction. Know how to set up ice tables to solve equilibrium problems: Be able to find the value of the equilibrium constant given initial conditions. Be able to find equilibrium concentrations of reactants and products given initial conditions and the value of K eq . Know LeChateliers principle. Be able to apply LeChateliers principle to reactions in equilibrium that are disturbed by changes in: partial pressure or concentration of a product or reactant. total pressure due to change in volume total pressure due to addition of inert gas. temperature Be able to predict the direction a reaction will proceed if it is at equilibrium and it is disturbed. Know the role of a catalyst in relationship to equilibrium....
