<tt>Quiz 3 will cover the following: Sections 14.1-14.4<br>
<br>
<b>Sections 14.1-14.3</b><b>:</b><br>
<br>
Know what rate is and how it is related to concentration (rate
law).<br>
Know what a rate law is and how you can use it, what the order is,
rate<br>
constant, etc. Know how reaction rates and stoichiometry are
related and<br>
how the rates of disappearance of reactants and appearance of
products can<br>
be realted to each other and the rate of the reaction (using the
balanced<br>
equation).<br>
<br>
Know how to obtain a rate from data and how to use rate data to
determine<br>
the rate law using the method of initial rates. This is shown in
the book<br>
in sample ex 14.6 (and the practice exercise) and my notes. You
really need<br>
to learn how to do this using the second example I used in lecture
(the long<br>
one). If you don't you will have problems with some of the
end-of-chapter<br>
exercises (especially the last one for section 14.3).<br>
<br>
Remember, rate laws can depend on concentration of reactants,
products and<br>
catalysts. The orders of substances in the rate law can be whole
numbers,<br>
simple fractions, negative (usually seen for products and
inhibitors). To<br>
get the overall order you simply add the orders for everything in
the rate<br>
law. Also, remember in general you can't write the rate law from
the balanced<br>
chemical equation. It must be determined experimentally. The
ONLY time you<br>
can write a rate law from a balanced eqn is if you know the
reaction is an<br>
elementary reaction (a single-step mechanism) and you don't know
this by<br>
simply looking at the reaction.<br>
<br>
<b>Section 14.4:</b><br>
<br>
Know what an integrated rate equation is for zero-order, 1st-order
and 2nd-order<br>
reactions and be able to use them. Know what the half-life is for
zero-order,<br>
1st-order and 2nd-order reactions. This is in section 14.4. The
equations<br>
for zero-order are in the notes and there are a couple of
questions in the<br>
chapter 14 "handouts" discussed in class and on the web (see
"notes" link)<br>
about zero and 2nd order. Be able to do the special problem
passed out in<br>
class and sent via e-mail.<br>
<br>
You can find the "handouts" mentioned above<br>

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