EXAM 1  Description

READ THIS GENERAL STATEMENT CAREFULLY:

            Your mission in this course is to obtain for yourself a useful working knowledge and understanding, at an appropriate level, of selected topics in general chemistry, as elaborated in your text and in class. The resources available to you include: the text, lectures and class handouts posted on this site, laboratory exercises, references in print and on the internet, consultation with the instructor outside of class, tutors, study groups, and whatever other legitimate means are necessary. There is no easy path to success. Put the work in.  It is particularly important to pay attention to the following:   chapter  summary,  key terms and concepts, and the assigned problems.  You will not be able to demonstrate adequate mastery of the material unless you understand the principles involved!  Similarly, you will find it pointless to memorize key terms without knowing what they mean and how they can be applied.

 “Right, sure, yeah, yeah, yeah – just tell us what’s going to be on the test, doc.”

What?  Questions designed to show if you have learned to use these principles and their associated language.

How?   Generally by means of objective questions in a variety of formats: fill-ins, short answers, matching, multiple choice, true-false, listing, categorizing, prioritizing, and problem-solving, drawing and/or interpreting diagrams, writing (and sometimes balancing) equations, completing tables, and making rational deductions are all highly probable possibilities.

With that in mind, a brief description of what you can expect follows:
 

Good stuff to know!!!

 

 

Zero Order

First Order

Second Order

Integrated Rate Law

[A] = -kt + [A]o

ln[A] = -kt + ln[A]o

1 / [A] = kt + 1 / [A]o

Half –Life

t1/2  = [A]o / 2k

t1/2  = 0.693 / k

t1/2  = 1 / ([A]o k)

Subjects from Ch 13 & 14 covered [in my own inimitable range of styles]

 

rate laws, reaction mechanisms, activation energy, collision theory, calculations

 

equilibrium constants, free energy, calculations

 

temperature effects

 

reaction profiles, kinetics, equilibrium, stability

 

killer modified true-false (Always, Usually, Sometimes, Rarely, Never)

 

vocabulary:  I define, you give the term 
 -- sort of like Jeopardy!, but you don't have to put it in the form of a question!

 

pretty much everything major will be hit in one way or another!
