Dudeeeeeee

omg

I feel so special

I thereby acclaim the sole power to put forward this chat at all fronts, to uphold and protect the dignity of Chemistry SE Chat, and to post almost all chemistry related stuff (allow me to tell you, that you can't trust me on that), and to draft my creative prescence so that you don't get bored reading.

Apparently you had written some equation based on fugacity or smth, could you suggest a good read on that? I am having a lot of trouble regarding physical chem lately. I have covered chemistry till JEE Adv level+a bit more, and now I want a structured read of more indepth chemistry (regarding chem olympiad).

But whenever I try reading something, it just feels either wayyy too off or I can't understand a topic at all. I realize the importance of a teacher at this stage, but sadly, I just don't have one currently eager for teaching olympiads.

@CuckooBeats
You are not special. I have just got bored....
:-P
(teasing)

Now really, you are special, but it is forbidden to tell you, so pssst!

Cuckoo Beats

I don't trust on Wikipedia anymore, in org chem, the more reaction mechanisms you know, the better. But I feel if you start reading wikipedia for physical chem, I just feel like stopping in a page or two, because its just off limits.....books are not helping me either....ira levine sir's book has given me some shocks of my life...I just get confused very often there LOL

@Poutnik ahahahaaa

Poutnik

Wikipedia is great if you know what to trust and what not to. And it is always great signpost of primary references, as original content is forbidden by W policy.

Cuckoo Beats

Oh

Poutnik

I bet libretexts is better for systematic studying.

Cuckoo Beats

14:14

If wiki has flaws....I don't know what in the world is perfect then :P

Poutnik

I very often use search delimiters.

Wikipedia is the general database running on wiki software. As there are many wikis, but one Wikipedia.

Cuckoo Beats

But you use it only when you know what your studying....my scenario as of now is- trying to find a way out in a thick forest

Poutnik

I often post to comments something like this, with substtituted placeholders

personally, have you checked any/did you find any university's lecture the best idk I don't have so much time to go through the whole database- chem.libretexts.org/Courses

there are more universities than many people I have been friends with

ahhh nvm

what i meant was, even if i tell every single friend of mine to go through, it wont work lol

Poutnik

Relation of fugacity to pressure is like relation of activity to concentration/molar fraction.

Cuckoo Beats

yes i know that, apparently i have been seeing this thermodynamic property \mu its sometimes electrochemical potential sometimes not.....and it is just rotting my brains because whenever I feel like I don't know a topic I just die wanting to know about it, this \mu thing has been haunting my dreams ever since

Poutnik

fugacity/activity is equal to relative pressure/concentration the substance would have, if it had ideal behaviour and still had the same chemical potential.

Cuckoo Beats

yes....ooo nice point I wanted to know what would happen in real gas conditions

Poutnik

mu=(dG/dn_i)_p,T,n_j,j<>i

Cuckoo Beats

14:23

ahhhhhh the formatting is so gross here

Poutnik

$\mu$

It is

Cuckoo Beats

nahh matjax wont work here

Poutnik

I know

Cuckoo works here. Even better.

Cuckoo Beats

OHHHH that was what mu was omgggg

Poutnik

Some great video lectures has Stanford university, but not sure about chemistry.

omgggg is a special India way how to cook and prepare eggs.

Cuckoo Beats

14:26

WDYM? This thing was cooking eggs earlier....

Poutnik

OHHHH then must be the interjection of entering nirvana eating them.

Cuckoo Beats

THANK YOU SO MUCH LIKE

like i literally got every single formula I was haunted by in my dreams here- chatgpt.com/share/67acb005-125c-8009-b91e-cdad5a40b315

Poutnik

ChatGPT is what it is, but it is pretty clever and handy if you do know what and how to ask.

Cuckoo Beats

obviously

ChatGPT is good in collecting info, not explaining them, there's a huge difference in that. I often make chatgpt do my home routine, make him say jokes (to increase my roasting capacity) and do my school project. But never never for studying topics

Poutnik

Also great in linguistics, like translations, text analysis and interpretation, suggestion for improvement, editorial stuff, changing of the style.......

Cuckoo Beats

14:32

yeahh

omg I gotta leave now, the board exams start from 15th and the first exam is english, but I shall come prepared reading abt this mu thing now

Poutnik

HAHA try this

chatgpt.com/share/67acb162-20a8-8008-8e54-b786076eee07

Or check next time

It is about you.

Cuckoo Beats

nooo imma check rn

bro....

I literally told chatgpt my sun and moon constellations, that guy freakin told every single thing about my life

Poutnik

:-D

Cuckoo Beats

XD

ok byeeeee

Poutnik

byeeee

Cuckoo Beats

16:13

So I gave a reading through it while dinner, it explains everything now, you could relate chemical potential with gibbs free energy, and the moment you do so, it opens up almost every other possible formulae which you would have used using gibbs free energy, seems like a powerful tool

Poutnik

Yes, CHP is the force behind most chemical changes.

Cuckoo Beats

hmmm

Poutnik

Exam wit excellent result I guess.

Cuckoo Beats

?

WDYM

Poutnik

I though you were in hurry to make exam....

Cuckoo Beats

16:17

uh no as i said the first board exam in on 15th

cbse.gov.in/cbsenew/documents/…

Poutnik

In context of physical chemistry, describe relation of chemical and electrochemical potential.
the latter uses the bar:

Sp tomorrow at my 1030 AM ?

Cuckoo Beats

sp...?

BTW just drop ya msg whenever you like, I would check it whenever I like....

Poutnik

I imply you biological AI is able to decipher my frequent typos :-P
One of my flaw is often pressing ENTER before check.

sp = so - 1 key aside.

Cuckoo Beats

okkayyy lol

ur 10:30AM is 3PM IST

don't worry all the QWERTY users get flaws B)

Poutnik

they wrote 1030AM IST

Cuckoo Beats

16:25

"they"....I thought I was taking to only one person

Poutnik

They = cbse.gov.in.
I thought there is more than 1 person.

Cuckoo Beats

Oh yeah basically we got some 60 yr olds checking our sanskrit papers in cbse

idk even in their seventies....who cares they give marks graciously, that is all what I care

BTW can you please explain why wikipedia is telling abt *swapped definitons* here:

*It is common in electrochemistry and solid-state physics to discuss both the chemical potential and the electrochemical potential of the electrons. However, in the two fields, the definitions of these two terms are sometimes swapped. In electrochemistry, the electrochemical potential of electrons (or any other species) is the total potential, including both the (internal, nonelectrical) chemical potential and the electric potential, and is by definition constant across a device in equilibrium, whereas the…

ughhh we dont have italics here?

Poutnik

Who said I dont?

like literally just a few lines later wikipedia defined electrochemical potential

OMG i gotta go

Poutnik

My domain may rules, my definitions...

It is like initial engineering/physics definition Delta U = Q - A
vs
chemical one Delta U = Q + A.
Note that physicists later accept Q + A too.

Cuckoo Beats

oohhh okk

thanks

Poutnik

Some may say that the sheep of physical chemistry is just a wolf of mathematics, coated by woolen chemistry coat with physical baseball cap......

Not sure if you know there what is sheep. :-P

It is a kind of a pig or a cow, which is more like fish or chicken. :-P

Or like a goat, but not so fussy.

"Does exist anything like India?" ... "No."

In the sense India is the set of various places, cultures and people..
