@@valorantyie9820 yes of course you can go to medical school as a chemistry major.....but as far as I understand he is doing chemistry calculations while already being in medical school, which is why I am confused. I'm not sure why in the world he would need to understand Gibbs free energy as a med student. And no I live in Canada so I do not need to take specific chem classes to go to most medical schools. However most medical schools do indeed have a chemistry requirement. For example a medical school could prerequire two introductory chemistry classes in which case I could do ochem and bio chem and completely ignore gen chem.

Thank you for your videos! You have helped me so much over the last three years. I am on my last assignment of chemistry for my degree, so I thought I should tell you what a positive impact you have had on my education. Thank you!

I don't know who you are man, but you are an absolute god in my eyes. You have helped me in all my physics classes, my chemistry classes, as well as my diff eq classes. I tip my hat to you, sir. You have saved my life multiple times.

Watching your calc playlist. Man you’ve been a massive help, thank-you!

your calmness kept me attentive throughout the whole lecture, thanks for being a good teacher

I use your videos to study, and to fall asleep to sometimes. Kinda like how it’s ten times easier to sleep in lectures than it is in my warm bed at night. Plus I get better in my chem class (maybe idk)

Started this chapter yesterday. You are so clutch❤️

Dear Organic Chemistry Tutor, First of all, many sincere thanks for your efforts! A. There is ONLY ONE BASIC, fundamental Energy Conservation and Transformation Law. It is definitely unique and conceptually indivisible delivering two logically joint concepts - these are Energy Conservation - and Energy Transformation. Still, a more-then-100-years-old conceptual failure has brought us to two separate thermodynamic laws - but this has nothing in common with the actual physics. To come back, they have coined two more fake thermodynamic laws, employed the Probability Theory + Mathematical Statistics, and this has helped formulate the Quantum Mechanics, which is thus a basically metaphysical conceptual construction and thus ought to be only restrictedly fruitful. B. By dividing the basically indivisible law, you are telling about Combinatorics, you are touching Probability Theory, you are even stepping back to Thermodynamics for a while, but... You are NOT answering the poser: WHAT IS ENTROPY, sorry! 1. In the formula S = kB * ln(Ω) you imply, Ω means not a "Huge Number of Microstates", not "Probability", which numerically ranges between [0,1], not even "Wavefunction", which ought to be a purely metaphysical notion, as it is... In effect, Ω ought to be a simplistic algebraic function of Lord Kelvin's Absolute Temperature. This result has been published 100 years ago in JACS. 2. WHAT-ENTROPY-IS-poser has been answered not by Clausius, not by Boltzmann, etc., but by Goethe, who has introduced Mephistopheles, the philosophical embodiment of ENTROPY. 3. Newton did basically know WHAT ENTROPY IS - A Counteraction. 4. That Counteractions do not grow to infinity with the growing Actions, but MUST reach their MAXIMUM values, is the result by Nicky Carnot formalized by Clausius... 5. In effect, Gibbs Energy formula renders implicit the interplay among ALL the relevant Actions (the Enthalpic term) and ALL the Counteractions (the Entropic term). 6. The standard approach you are reporting about is OK for the implicit Enthalpy-Entropy picture, employing it for studying reaction mechanism details is likewise eating soup with fork.🧐

Indeed, you are truly godsend!

The timing of this is…pheNOMenal

How could we assume that Kp equals to Kc with the question number 9?

Thnkss bro❤

I really enjoy the videos. I have a question on this one. You discuss K the eq, constant, and say K=1 at equilibrium. Is that not false? K can equal any number of value at equilibrium. I understand that we can use whether K 1 to determine whether it is reactant or product favored, but a K=1 would only tell us the concentrations are equal, not the rate of reaction. Am I misunderstanding this?

On the third problem, on the dealta S reaction, why were the reactants minus each other to get 20 J/mol?

If u have an endothermic reaction (delta H is positive) like H2 + I2 --> 2HI can you say whether the entropy rises or decreases and whether the reaction could be spontaneous?

@byebrows9698

Жыл бұрын

Assuming the reaction is endothermic in the forward direction, the system requires work. Hence, the reaction is non-spontaneous meaning the Entropy of the universe is negative. If you watch this video, you will see the answers for yourself: kzread.info/dash/bejne/noJqmKhyhpqTj7Q.html

Can anyone explain for a combustion reaction where ΔSsystem is positive and ΔH is negative, even though I know the reaction will always be spontaneous, how do I determine if lowering the temperature makes it more or less spontaneous? If ΔG=ΔH-TΔS then lowering the temperature would make ΔG less negative and less spontaneous but since ΔS surroundings=-ΔH/T approaches infinity as temperature decreases then the entropy of the universe contradicts this and implies that lowering the temperature makes the reaction more spontaneous. So if I wanted to know if lowering the temperature makes the reaction more or less spontaneous which do I look at, ΔG or ΔS of the universe. Why are they contradicting each other?

respectable

No one comprares to how well he teaches

i think you'll find for the starting question that the answer is E. None of the above is false - since D. is false.

how did you get the negative -109.7?

bro you are amazing but you just need a better microphone

Im gonna go ahead and offer you a job at my school.

One question if someone might be able to help: I came across the terms "desolvation penalty" and "rigidization penalty" in binding events which were both labelled as entropic penalties. The second I understand, as rigidization decreases the number of microstates of the system. But how does dehydration present a positive entropy term? Shouldn't the release of water in the system be a favoured entropic event, by allowing for more degrees of freedome as compared to water being forced in an order manner around an undefined molecular surface? Would be glad if someone could help out. All the best!

Just take my tuition

In the first question you actually also have that "E" is a false statement :-)

@zememerr2329

2 жыл бұрын

To convert to Kelvin, add 273 (technically 273.15 but the extra decimals tend to be negligible) to your Celsius temperature. 298 Kelvin is a very common temperature in chemistry, it’s the standard temperature value (that or 25° Celsius, they’re the same thing)

those gibbs value are for the reaction not the compounds. As a result, once the equations are rearranged instead of subtracting products and reactants (which i am guessing u did) to obtain the gibbs value for the final equation you need to just add those two earlier reactions.
