    Data Van der waals
AI Thread Summary
The discussion revolves around calculating the approximate molecular volumes for CCl4 and CH4 using the Van der Waals equation and Lennard-Jones potential parameters. Participants emphasize the need for guidance rather than just encouragement to try harder, expressing frustration with the lack of clear explanations from professors. The provided Lennard-Jones parameters for chlorine and hydrogen are highlighted as essential for the calculations. There is a call for step-by-step assistance to facilitate understanding and problem-solving. Overall, the thread reflects a desire for practical help in applying theoretical concepts to homework problems.

Homework Statement



Based on values for the Van der Waals equation tabulated in Table 1.6 in
appendix A, determine an approximate molecular volume for CCl4 and CH4.

Rationalize these values based on reasonable bond lengths and other
parameters. The Lennard-Jones potential energy function is often used to
model interactions between molecules.

Homework Equations



V(r) = 4ε [{σ/R}^12 - {σ/R}^6]

For Cl, ε = 357/k, σ = 4.115 Angstrom
For H, ε = 33.3/k, σ = 2.968 Angstrom

That doesn't count as an effort. Try harder.
 
C'mon, I'm coming here for help, not to be told how to study. I learn when things are explained to me which, ironically, most of my professors fail to do. At least give me a step forward in the right direction so I can quickly solve the problem. I don't have time for a thorough comprehensive reading on the subject.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
