I am taking an undergrad course P Chem II: Quantum Chemistry and Spectroscopy...and the final is a standardized exam from the ACS. I was just wondering if you guys had any tips or knew where to find old exams to practice with. I just was looking for any advice in general too. Thanks a bunch!

Homework Statement Consider the one dimensional space in which a particle can experience one of three potentials depending on its position. They are: V=0 for -\infty<x\leq0, 0, V=V_{2} for 0\leqx\leqL, and V=V_{3} for L\leqx<\infty. The particle wavefunction is to have both a component...

Hello all, I've just started a class in physical chemistry and it seems to be progressing fairly slowly so I thought I'd start a thread so we could discuss some key concepts that are frequent in physical chemistry. Keep in mind I haven't taken any courses in thermal dynamics yet so I am...

Calculate the final temperature of a sample of carbon dioxide of mass 16.0g that is expanded reversibly and adiabatically from 500mL at 298,15K to 2.00L. I know the answer and understand how to do the problem except for 1 part. The equation to get the solution is : Tf = Ti (Vi/Vf)^(1/c)...

Is it just me or do other people think the atkins physical chemistry book is absolutely detrimental for undergraduates? Unless one is sound in their physics, chemistry, and math and the student is using the book as a means to find out other perspectives on chemistry issues, atkins is not...

Physical Chemistry Help! Homework Statement Hello TT forum. Finals are coming up!...and i am having a hard time solving these stoooooopid physical chemistry problems. ..any help would be GREAT appreciated! These are the 4 problems i am having a hard time with. I put ======= to separate each...

Hey. I currently have a copy of atkins physical chemistry, although it is fairly old (4th edition). I found it for $20 at a second hand bookshop and it isn't in the best of conditions, but it has done the job so far! Anyway, what I am wondering is, are the later editions (8th i think?) much...

The boiling points of three compounds are: CH3OH, 65C; CH3Cl, –24C; CH3Br, 4C Discuss the relative strengths of the intermolecular forces in liquid samples of these three compounds. what should I include in my discussion?

Homework Statement a student carried out a photoelectric experiment by shining visible light on a clean piece of cesium metal. She determined the kinetic energy of ejected electrons by applying a retarding voltage such that the current due to the electrons read exactly 0. The condition was...

If I failed this courses should I write a supplementary in about 10 days or should I retake it and put myself behind a full year of studies in my program?

HI, I have my exam in 2 days and I am wayyyy behind this course I'm am only looking for a pass since I cannot get it down...I was just wondering if anyone had any advice on how to tackle it all? Should I do problems from every chapter and try and get through it? Or is there a better method you...

Hey. Next semester i plan on taking a unit on inorganic and physical chemistry. At the moment my collection of chemistry textbooks is a bit miserable (consisting of only my high school chem book) so id like to add to it. I will purchase whatever textbook is required for the course, but i...

I managed to get through a physics for bio majors type class with very little understanding of mechanics. I didn't put much effort in because at the time I was a biology major. Now I'm more interested in chemistry and will soon be taking the dreaded physical chemistry. I am curious how...

Ok so I just started this course and we have to so review from first year stuff but I am completely lost and have no idea how to do the questions. There are a bunch so could someone just run through one with me please? Commercial aqueous nitric acid has a density of 1.42g/mL and is 16.0mol/L...

Physical Chemistry Problem! The total pressure of a mixture of oxygen and hydrogen is 1 atm. The mixture is ignited and the water is removed. The remaining gas is pure hydrogen and exerts a pressure of 0.4 atm when measured at the same values of T and V as the original mixture. What was the...

Is calculus based physics harder than physical chemistry? Just curious. I've taken p-chem I (basically calc-based derivations of the laws of thermodynamics, chemical equilibrium, phase transitions, colligative properties, and electrochemical principals) and was wondering if this was harder...

Hello, I'm taking Physical Chemistry I in second year, and my prof does not have a required book for the course and everything will be based off his notes (which are very good by the way) However, I would like a deeper understanding of the material, and the prof did recommend two books. What...

[SOLVED] Physical chemistry problem Homework Statement A closed vessel of 5L volume is kept at 80 degrees celcius and contains a mixture of two liquids A and B dissolved in a solvent, with their initial concentrations [A]=0.1mol/L and [B]=1.0mol/L. The volume of the gas phase is 2L and it...

Hi, I am looking for any physical chemistry textbook without a lot of calculus. I have been looking at physical chemistry for biological sciences but I am unsure if they cover the same topics as the regular atkins and other physical chemistry do. Does anyone have any suggestions for good books...

Homework Statement In a closed system shown in the Figure below (http://i18.tinypic.com/7x1r8mo.jpg"), the piston is freely moving without friction and the system is initially filled with gaseous molecules A only. The mass of a piston is 100 g, its area is 10 cm2 and it is 10 cm from the...

Homework Statement Im doing an A-level project on the Schrödinger equation and am unsure on the mathematics used to obtain the following results: The Schrödinger for a particle in no potential field (=0) has the solution: psi(x)=e^ikx. i is defined below, I haven't really a clue as to...

hello all, I am doing some homework and need some verification on the math: [Px, Px^2]f= PxPx^2f - Px^2Pxf Px= -iħd/dx Px2= -i^2ħ^2d^2/dx^2 -iħd/dx(-i^2ħ^2d^2/dx^2f) - (-i^2ħ^2d^2/dx^2)( -iħd/dxf) i^3ħ^3d/dx(d^2f/dx^2) - i^3ħ^3 d^2/dx^2(df/dx) the number following the "^" sign...

My professor asked us to think of ideas to do a quick computational project in physical chemistry (he says quick because there are only a few weeks of school left). I will be using the student edition of the Spartan P-Chem software. I really don't have any idea what I should do. I prefer...

I really need help with the following question, If the work function of Rb is 2.09 eV, what is the number of electrons ejected, their energy in eV, and their velocity, from a microjoule pulse of 500nm laser light?

Sir, What is the general formula to find the ionization energy of elements?

Opinions on this one? Specifically for the QM uninitiated. If you have other recommendations for better clarity, please comment. Thx. A.

I am considering taking Physical Chemistry next semester but my Physics courses at community college did not have quantum mechanics (so I have to take the quantum mechanics part of physics for part of the semester in Fall as well.) So, is it a death wish to take Phys. Chem w/o having taken...

What subjects would you be required for doing a physical chemistry degree in university? Im thinking of chemistry (obviously ), and maths, and maybe physics. But anything else?

Sorry for my overall ignorance, members. What career options does Physical/quantum chemistry degree/ Ph.D give you as a general?

Hello all I'm thinking of maybe doing physical chemistry in university (currently I'm 16) but as i am currently doing AS- level, I've chosen maths, biology, Chemistry, and Design technology. Now the above subjects would be somewhat, pointed towards medicine, however, I'm not that keen on...

I'm actually taking a physical chem course and i have to hand in a report onpartial molar volumes in NaCl solutions...I'm not really sure how the concept works and I'm wondering if anyone could clarify! Thanks

I've yet to clearly understand the difference between these two disciplines, and I was wondering if anyone else had any insights. I first thought they were one and the same, but they are certainly used as different terms in most universities. I've come to understand it as a difference of...
