PLEASE HELP! Chemical decomposition question(s)





COULD SOMEONE PLEASE SEND ME A LINK OR SOMETHING ON CHEMICAL DECOMPOSITION RATES PLEASE?

Got to work, I WILL check this tomorrow. Thanks everyone;)

emh, oki mate, but really it isn't necessary to share you life/current health situation for a question like that, just sayin'.
about the question, chemical decomposition of what? really there's ins't an answer to your question as you asked it.
speaking as simply and unspecific as possile, the decomposition rate of a compound depends on its nature and temperature, so you at last need to tell us the compounds you are interested and the conditions you are working with.

for example, the chemical decomposition of pvc in a wall is vastly slower than of a pvc pipe under the sun in a desertic location.

TL;DR: question too broad, no way of answering without more details

Let me refine that ?


What is the most popular, user friendly database just to look up a chemical structure/ specs? Preferably that show a picture of the molecule?

Ubya; Thanks. I knew that and figured it out. Was just in a hurry as usual.

i mostly use pubchem, if you don't know the name of a molecule, you can just draw it on their website and you'll find the right page plus pages for similiar molecules
https://pubchem.ncbi.nlm.nih.gov/

Wikipedia ?
+ Most popular
+ User friendly
+ Most of the time shows compact and expanded views of the molecule
+ Lists most properties if not all, solubility, metling point, NFPA, CAS...
- NOT always reliable. Some critical thinking and more googling can be necessary.

About that last point, when properties are different between languages you KNOW something is wrong and deserves to be checked.

I dont see how that would be relevant to decomposition rates though.
If you want to read more about such or such compound, patents sometimes are interesting and so is Researchgate.

Ubya, I loved your PVC example :)
