<br> Definition: If you apply a stress to an equilibrium problem, the system will try to get rid of that stress in order to go back to the original equilibrium.<br> <br> Mr. <nowiki>McLeod</nowiki> addition to definition:<br> <br> a. System can only overall make more reactant or more product<br> b. System will never get back to original equilibrium (since you add something in) but comes to a new equilibrium.<br> <br> <br> <br> How you answer <nowiki>LeChatlier's Principle problems for Mr. McLeod</nowiki> ($ step method)<br> <Br> 1. What is stress<br> 2. Reduce stress by which causes making more reactant or product<Br> 3. Favors the forward or backward reaction (for change in temp must add endo or exo)<br> 4. Shift equil to the Right or Left<br> <br> <br> For AP students (how actual amount of material change??):<br> <br> <br> <br> <br> <b>Types of Stresses</b><br> a. Adding more reactant/products<br> <Br> <Br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> b. Changing Temperature (really means increase Energy). <br> <Br> <Br> Example from class:<br> <br> <Br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> c. Pressure change (there are more than one way to do this)<br> <br> <Br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> d.
