Stoichiometry tables 
Rate laws

Fogler: Chapter 4


This game focuses on rate laws and stoichiometry, allowing the students to master the elements of the stoichiometric table: 



  The interactive portion of the game 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 game 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. 


Students report that they find this game 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 game.  We have been unable to determine the circumstances that give rise to this effort. 

Some students comment that the 25 second 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.
