Concepts  Arrhenius equation 
Stoichiometry tables 
Rate laws
Time 36 minutes ± 16 minutes
Reference Fogler: Chapter 3
 
Description		 This module focuses on rate laws and stoichiometry, allowing the students to master the elements of the stoichiometric table: 

 

 

The interactive portion of the module is similar to that in Kinetic Challenge 1.  Students can choose from four categories (reactants, products, rate law, potpourri) and four levels of difficulty (200-1,000 points). Each question has four multiple-choice answers, and students have a limited amount of time to make a response: 

 

 

The goal of this module is to provide the students with practice setting up stoichiometric relationships, so that they will avoid mistakes, such as expressing the reaction rate law for an irreversible reaction as if it were reversible, or using the ideal gas law for liquid-phase reactions.
 

Grade Base The game score is the number of accumulated points, including gains or losses from Double Challenge and Final Challenge.  For the performance scores, the student is given 3 points for every correct answer in the 200-600 point range, and 7 points for the 800-1,000 point questions.  The Final Challenge question is worth 8 points. 
Comments Students report that they find this module very useful as a review before the first examination.  In some instances, some of the text strings in the last few questions and the Final Challenge question will become garbled, and the computer will lock up at the end of the module.  We have been unable to determine the circumstances that give rise to this effort. 
Some students comment that the one minute time limit does not allow them enough time to derive the required expressions.  It is helpful to suggest to students that they examine the four options available and choose the correct answer by process of elimination, based on the information provided in the problem statement, rather than trying to derive the expressions.
Installation  Instructions for installing and using the ICMs are available.
