Mechanisms and Rate Laws - Advanced

Please note: This page has a code bug which occasionally moves the "Total Done" count up without warning. Using this page in the Firefox browser is highly recommended; the bug does not appear in this browser (April 2015.)

This page will provide exercises in relating reaction mechanisms to the appropriate rate laws. When you click "New Problem", a large window will open. In that window, which you may have to relocate, you will find an overall reaction, the reaction mechanism and a generic rate law for inputting your answer. The presentation has the following format:

• The system is completely homogeneous, so all species shown have variable concentrations.
• All processes preceding the rds (rate determining step) are rapidly attained equilibria.
• The observed rate law will only contain species identified as reagents in the overall reaction.
• To submit the answer, use the select boxes after each species to enter the orders.
• Use the "Check Rate Law" button before submitting your answer. This will open a small window with your proposed rate law in it.
• When you are satisfied with your rate law, press the "Submit" button. Results appear on the main window.
