Physical chemistry? Does anyone know about a good physical chemistry study guide? I'm taking this class this semester, and I need some extra help. I've heard abouth the Schaum's study guide, but some say it's kind of confusing.

For Those Who have taken Organic Chemistry and Physical Chemistry in College, which is harder? I have just taken my Organic Chemistry Final Exam. After two semesters of organic chemistry, I have to say this is the hardest class I have taken because of the volume of information that I have to memorize. I have already scheduled Physical Chemistry for the fall semester, and I am asking those who have taken both Physical Chemistry and Organic Chemistry in college. Which is harder, and...how much harder is it than the other? Should the blood the sweat I poured into Organic Chemistry help me in Physical Chemistry?, or will I be in for a rude awakening?

(unrelated question) How do you read on chemistry and other physical science? I think I read rather slow beacuse of my attention span and bad short term memory. How can I get better at reading? How can I read faster but at the same time remember more? Im not going to do anything this summer and I want to take sometime to read a whole general chemistry book, to refresh my memory on old basic stuff and learn new stuff(hopefully prepare for physical chemistry: thermodynamics and advance inorganic chemistry for next semester). But I suck at reading?!?

I am taking physical chemistry and we are using partial derivatives, I have never solved partials and need? a little help.The problem reads: p=RT/V + (a+bT)/V^2 a and b are constants. Find (dV/dT) holding p constant. dV/dT is a partial derivative. It is a physical chemistry problem where we are looking at volume with respect to temperature while holding pressure constant. I attempted to isolate v, however I could not. Explanation would be helpful because I need to understand the process so I can repeat it in the future. Thanks in advance.

In physical chemistry why does the boiling point increase with pressure? In physical chemistry, we learn that the boiling point of a matter (liquid or solid) increase when pressure is applied to that. Can someone tell me how.

Whay are all organic, inorganic and physical chemistry textbooks wrong? All organic, inorganic and physical chemistry textbooks (that I have gotten my hands on) have been wrong about orbital theory. Valence shell electron pair repulsion (VSEPR) theory includes the hybridization rules we all learned (sp^3 hybrids, etc), but they don't exist. Worse, no textbooks give a disclaimer that VSEPR theory is a simplification that help visualize and solve problems, but hybrids don't exist in nature. If you study carbon-carbon bonds (i.e., photoemission spectroscopy) you will clearly resolve separate p and s orbitals for carbon; you won't see a mix like reasoned in hybridization theory. So why do we still teach this? VSEPR came about in the late 50s, and this contradiction has been know about since the late 60s, but every textbook remains wrong. Why?

Physical chemistry or organic chemistry? I'm only in highschool, though I''m doing the IB Higher Level chem course which is considerably more intensive than regular chme. I have the option of choosing an elective subject in my chem class. Either organic chemistry or further physical chemistry. We've already done a fair bit of both last year. But now we have to choose. It'll mostly be energetics and kinetics for p-chem and reactions for o-chem. My question doesn't really have to relate to my current situation. I was just wondering in university, which of the two do you consider to be harder? Would someone who majors in biochem have to do p-chem? I know that o-chem is absolutely necessary for biochem.

Physical chemistry: spawn of satan or not that bad? Ok, basically I have a choice between a BA in chemistry and a BA in biology. I need to stress that I will /not/ use the degree regardless as I plan to apply to medical school and they could care less what your degree is in. That being said, I like both biology and chemistry, yet I am hesitant to commit to chemistry since at UC Davis (where I plan to transfer), and im sure elsewhere, you're required to take a full year of physical chem as part of the degree requirements. I hear that it is obviously very heavy in physics and is extremely hard. So my question is to those who are chemist majors who preferably have already taken one or more physical chem classes: Is it really that bad or not? As much description of pchem as you want will be much appreciated, however, keep in mind that I'm just finishing gen chem 1 so I may not understand any terms you use that are specific to organic or physical chem. Thanks!

Physical Chemistry Questions? For the following, determine the direction of energy transfer and describe it as work and/or heat. Explain your reasoning: A)A person goes swimming in cold water. B)A truck pulls a trailer. C)The explosion of gasoline in an engine cylinder pushes the piston and increases the temperature of the engine. Using Hess's Law and the following three equations, derive the equation for the combustion of gasoline: 2 C8H18 (l) + 25 O2 (g) → 16 CO2 (g) + 18 H2O (g). Describe the your process by using 1, 2, or 3 instead of their respective equations and calculate the enthalpy change for the reaction. 8 C (s) + 9 H2 (g) → C8H18 (l) H = –268.8 kJ C (s) + O2 (g) → CO2 (g) H = –393.5 kJ 2 H2 (g) + O2 (g) → 2 H2O (g) H = –483.6 kJ A)Determine whether your final equation is exothermic or endothermic. B)Evaluate (no calculations) the sign for the change in entropy for the final equation. C)Considering your answers to parts b. and c., will the reaction be spontaneous?

Physical chemistry problem? The vapour pressure of a volatile liquid can be measured by saturating a gas by flowing it slowly through the liquid and measuring the weight loss of the liquid. In such an experiment 5L of dry nitrogen at 760 torr was passed slowly through geraniol oil, which has a molar mass of 154.2g/mol. The temperature was held constant at 110 Degrees celcius. The mass loss of the oil was 0.32g. Calculate the vapour pressure of geraniol oil at 110 degrees celcius. Basically i can't find a relevant equation to help solve this problem, and there is no mark scheme for me to find a solution unfortunately! Would appreciate any help with this problem, its driving me insane! Thanks so much, i think maybe i was looking to overcomplicate the problem. Just one more thing, the answer i got, 1.29Kpa, does that sound reasonable?

Physical Chemistry Help? Unfortunately, most of the energy released from the combustion of gasoline is lost as heat. It is only the energy converted to work that moves your vehicle. Consider the following data: # of moles of octane used, Amount of heat released 1.3 , 4600 kJ 6.8 , 24060 kJ 24.4 , 86340 kJ 31.9 , 112880 kJ A) On your own paper create a graph of heat released vs. moles with a line of best fit. Calculate the slope of your line. What does it tell you? B) What percentage of the total amount of energy (5055 kJ/mol) is being released as heat? What % is being converted to work? C) A small home requires about 35,000 kJ of heat to stay warm on a cold day. If a car uses 45.0 gallons of gasoline, how many days could the house stay warm from it if it could use all the wasted heat? We will assume for now that gasoline is pure octane. (Density of gasoline/octane is 0.702 g/mL; 1 gallon = 3.7854 L; mw C8H18 = 114.26 g/mol)

Physical Chemistry Question? Prove that wavefunctions Psi_1 (quantum number n =1) and Psi_2 (quantum number n = 2) for a particle in a one-dimensional box are orthogonal to each other. This proof requires some clever integration.

Physical Chemistry Question, please help me..? A cloud mass moving across the ocean at an altitude of 2000m encounters a coastal mountain range. As it rises to a height of 3500m to pass over the mountains, it undergoes an adiabatic expansion. The pressure at 2000 and 3500m is 0.802 and 0.602 atm, respectively. If the initial temperature of the cloud mass is 288 K,what is the cloud temperature as it passes over the mountains? Assume that Cp,m for air is 28.86 JK^-1 mol^-1 and that air obeys the ideal gas law. If you are on the mountain, should you expect rain or snow?
