Chemical Kinetics: do not understand anything

Click For Summary
SUMMARY

This discussion centers on the challenges of understanding chemical kinetics, specifically the determination of instantaneous reaction rates. Participants emphasize that exact instantaneous rates cannot be calculated due to the vast number of particles involved in reactions, approximately 1022. Instead, they suggest focusing on average rates and graphical approximations, such as tangent lines, for better comprehension. The conversation also highlights the inadequacy of the teacher's background in chemistry, as they hold a degree in English Literature, which complicates the teaching of complex scientific concepts.

PREREQUISITES
  • Understanding of basic chemical kinetics principles
  • Familiarity with calculus concepts, particularly derivatives and tangent lines
  • Knowledge of quantum mechanics fundamentals
  • Experience with graphical data representation in scientific contexts
NEXT STEPS
  • Study the concept of average reaction rates in chemical kinetics
  • Learn about graphical methods for approximating instantaneous rates
  • Explore quantum mechanics and its implications for chemical reactions
  • Review rate laws and their applications in chemical kinetics
USEFUL FOR

Chemistry students, educators in science, and anyone interested in the complexities of chemical reaction rates and their mathematical representations.

Homework Statement


Our chemistry teacher just learned about chemical kinetics. I've been working with the calculus teacher to find out how to determine instantaneous rates exactly. We don't have any equation. Could someone explain this please?

You can't find instantaneous rates exactly. Chemical reactions take place between \approx 10^{22} particles, the only meaningful quantities are averages.

Even if you're looking at a single set of molecules in a reaction, the exact rates depend on detailed quantum mechanical calculations---I assume this is outside the scope of what you're looking for.

Can you be more precise in what you want to learn / achieve? Or what exactly you're having trouble understanding?
 
"Our chemistry teacher just learned about chemical kinetics"
this statement bothers me on many levels. Are they trying to teach it now? As stated above, I am not sure of your question.
 
instantaneous rate of a reaction can't b found exactly......as far as i know
reactions deal with the changes in quantities which rarely have any independent existence.
Also these changes constitute energy absorption/release in many ways...light, heat most probably in heat. combining all these phenomenon n restricting them to a single equation is something that just can't be imagined...but may be oneday we may succeed in doing so!
 
Our chemistry teacher actually has a degree in English Literature. We have no budget. I bought a few textbooks online and taught him the rate laws, etc. I also showed him a graphical approximations for finding tangent lines. I go to a public school. We have no budget.
