“What were some science facts that supported the theory after it was developed?”
“Did anyone catch the name of the other theory that was in use?”
“Describe the thought processes behind Rumford’s experimental design.”
“After the cannon tests, was Rumford satisfied that he had greatly weakened Caloric theory and put out a strong alternative theory?”

Chemistry Essay Assignment
LeChatelier’s Principle
April 4, 2024
READ AND FOLLOW THE DIRECTIONS!
LeChatelier’s Principle: If a system at equilibrium is subjected to a stress, the equilibrium is shifted to the direction that relieves that stress.
Either write a 5-7 paragraph essay, or prepare a speech-and-slideshow with a similar amount of information, to compare LeChatelier’s principle in chemistry to how the same principle plays out in other settings (biology, economics, politics, basketball, youth group, etc.). You will not actually have to give the speech, but I will give 10 points extra credit if you do. You might present the speech outside of class time, depending on how many people choose this option.
You may either demonstrate one example in a non-chemistry setting, and discuss 2-4 aspects (one paragraph each) of that example, or more likely, 2-4 different examples, with each example probably forming one body paragraph.
For each component of one example, or for each example, discuss either how the principle is demonstrated and what the subsequent shift is; or how you would predict that a specific hypothetical stress would produce a specific shift. For both the chemistry example and the non-chemistry examples, present clear and detailed explanations of how the stress leads to the shift.
Your first body paragraph must include a clear example and explanation of LeChatelier’s Principle in chemistry. The essay must have good introductory and conclusion paragraphs (or slides, if a speech and slideshow), good organization and flow to the essay (or slide show), and good grammar. If you are going to present a speech, you need to type a manuscript of that speech.
Type in Google Docs, and if you are presenting a slide show, present in Google Slides. Submit your finished work by sharing it with me at craig.sandeno@dc.asenctcolorado.org and setting the button just below the Share button (in Google Docs) to Editing.
