  1. Read the introduction of "Chemical Equilibrium" at http://vax1.bemidji.msus.edu/~chemistry/equilibria.html, and then consider the following:
    1. In the Haber process problem, the equilibrium constant was determined to be 0.51 at 400°C. If the reaction was written as 1/2 N2 + 3/2 H2 --> NH3, is the equilibrium constant the same?
    2. Do the last problem on the page and then determine whether an increase in temperature increases or decreases the equilibrium constant. Can you deduce anything about the enthalpy change for the reaction?
molecular equilibrium http://edie.cprost.sfu.ca/~rhlogan/molec_eq.html
  1. Another general chemistry topic presented at R.H. Logan's page is molecular equilibrium. Read through the material at http://edie.cprost.sfu.ca/~rhlogan/molec_eq.html, and answer the following:
    1. What is one sure sign that a reaction is irreversible?
    2. What example does he give for a homogenous molecular equilibrium?
    3. Write the equilibrium constant expression for this reaction.
    4. Why is water ignored in equilibrium expressions?
    5. How does LeChatlier's principle relate to equlibria?
    6. Suppose you wanted shift the equilibrium to the right. Would a catalyst be of any use?
equilibrium http://vax1.bemidji.msus.edu/~chemistry/equilibria.html
  1. Bemidji State University provides help on equilibria with explanatory text and step-by-step problem solving of related questions. Study the material on equilibrium at http://vax1.bemidji.msus.edu/~chemistry/equilibria.html, and answer all of the questions specified to be done on your own.
