139H CHM TUTORIAL 6 CH17
You should be able to do any of the following questions from the Silberberg textbook (6th edition). You
may not need to do all of the questions! Do as many or as few as you feel is necessary to achieve an
understanding of the pertinent concept(s). You are the best judge of your own learning!
Please note that the questions given below have full solutions in the Student Solutions Manual. The
solutions manual is best used to check your final answers, rather than to provide you with step-by-step
prescriptions to answer each question. In other words, it is important that you be able to work through
the problems and achieve the correct final answer by yourself (active learning) rather than using the
solutions manual to show you how each question might be answered (passive learning). Learning how to
solve problems in science comes through active practice; don't allow the solutions manual to do the
work for you!

7, 8, 14, 18, 25, 26, 27, 29, 33, 35, 38, 43, 45, 51, 59, 69, 71, 76,

Note: problems appearing in bold face incorporate multiple concepts in a single question, and are
therefore the more challenging ones.
In addition, the following problems will also be discussed in next week's CHM139 tutorials:
1. Problem 17.51
2. Final 2009S
At 1800K, oxygen dissociates very slightly into its atoms.
O2 (g)
2O (g)
Kp=1.2 10-10
(a) Calculate Kc for this reaction.
(b) You place 1.0 mol of O2 in 1 10.0 L vessel and heat it to 1800K. At equilibrium, (i) what is the molar
concentration of O2? (ii) How many oxygen atoms are presented in the flask?
(c) The volume of the reaction vessel is reduced to 5.0 L. Does the reaction favor reactants or products?
Calculate the partial pressure of O2, in units of atm, after equilibrium re-establish.
