    Energy Rotation
AI Thread Summary
The discussion centers on understanding the energy barriers associated with the rotation of carbon bonds from anti to gauche conformations. It clarifies that the magnitude of these barriers refers to the energy difference between the two states, specifically the energy required to overcome the barrier during rotation. Participants emphasize that the energy of the individual conformers is not relevant to calculating the barrier; instead, one should focus on the energy difference between the anti and gauche forms. The conversation highlights the importance of using provided values for accurate calculations. Understanding these concepts is crucial for solving related homework problems effectively.

Does 'magnitude (in kJ/mol) of energy barriers to rotation from anti to gauche' mean the difference in energy?
This question is asking for the magnitude of energy barriers to rotation about the bond between two carbons from anti to gauche. Do I just subtract gauche energy from anti?

What is the difference between the two conformers? Use actual values only if you are provided with them.

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...
