Quiz 3 material (14.1-14.4)

[robert zellmer]

Quiz 3 will cover the following:  Sections 14.1-14.4

*Sections 14.1-14.3**:*

Know what rate is and how it is related to concentration (rate law).
Know what a rate law is and how you can use it, what the order is, rate
constant, etc.  Know how reaction rates and stoichiometry are related and
how the rates of disappearance of reactants and appearance of products can
be related to each other and the rate of the reaction (using the balanced
equation).

Know how to obtain a rate from data and how to use rate data to determine
the rate law using the method of initial rates.  This is shown in the book
in sample ex 14.6 (and the practice exercise) and my notes.  You really need
to learn how to do this using the second example I used in lecture (the long
one).  If you don't you will have problems with some of the end-of-chapter
exercises (especially the last one for section 14.3).

Remember, rate laws can depend on concentration of reactants, products and
catalysts.  The orders of substances in the rate law can be whole numbers,
simple fractions, negative (usually seen for products and inhibitors).  To
get the overall order you simply add the orders for everything in the rate
law.  Also, remember in general you can't write the rate law from the 
balanced
chemical equation.  It must be determined experimentally.  The ONLY time you
can write a rate law from a balanced eqn is if you know the reaction is an
elementary reaction (a single-step mechanism) and you don't know this by
simply looking at the reaction.

*Section 14.4:*

Know what an integrated rate equation is for zero-order, 1st-order and 
2nd-order
reactions and be able to use them.  Know what the half-life is for 
zero-order,
1st-order and 2nd-order reactions.  This is in section 14.4.  The equations
for zero-order are in the notes and there are a couple of questions in the
chapter 14 "handouts" discussed in class and on the web (see "notes" link)
about zero and 2nd order.  Be able to do the special problem passed out in
class and sent via e-mail.

You can find the "handouts" mentioned above
(Chapter 14 - Chemical Kinetics - Handouts) at

*Homework coverage (you should be able to all problems in the given 
ranges)**:

*For those of you using the 14th edition the quiz covers sections 14.1-14.4
You should be able do to homework problems 14.1-14.8, 14.17-14.50,
14.89-14.103, 14.117

For those of you using the 13th edition the quiz covers sections 14.1-14.4
You should be able do to homework problems 14.1-14.8, 14.17-14.50,
14.89-14.103, 14.117

For those of you using the 12th edition the quiz covers sections 14.1-14.4
You should be able do to homework problems 14.1-14.8, 14.17-14.52,
14.97-14.109, 14.119

For those of you using the 11th edition the quiz covers sections 14.1-14.4
You should be able do to homework problems 14.1-14.6, 14.13-14.46,
14.83-14.93, 14.104

For those of you using the 10th edition the quiz covers sections 14.1-14.4
You should be able do to homework problems 14.1-14.5, 14.11-14.44,
14.81-14.89, 14.98

*For the on-line homework:**
*
Do ch 14 tutorials 1 (14.1-14.4)
and the ch 14a (14.1-14.4) homework review.

Both of the above are for credit.

There's a couple of DSM module which cover ch 14 material.  These are 
NOT for credit.

Make sure you can do the assigned textbook questions, the tutorials and 
the homework
review questions.


Don't forget the *extra homework problems* discussed in class.  They can 
also
be found on the web at the Notes link (see above) or Homework link where you
will also find the solutions (CH 14 - Kinetics, Extra Problems and 
Solutions),

*CH 14 - Kinetics, Extra Problems and Solutions* 
<https://www.asc.ohio-state.edu/zellmer.1/chem1220/homewk/ch14hmwk_add.pdf>


You will get the integrated rate equations and half-life eqns. on the quiz.
They will not be in any particular order nor will the half-life eqns
necessarily be in the same order as the integrated rate equations.
