Unfortunately not, our prof. didn't recommend any textbook. I was searching for a good textbook but I couldn't find helpful books, more specifically I couldn't find a textbook which includes exactly the topics we are discussing. Therefore, I had difficulties solving problems. Furthermore, we...
But which equation do you mean? In statistical physics course we didn‘t calculate the molar entropy which is why I have struggles finding the right equation.
But in general you calculate molar quantities with this Sm = ∆S/n
I mean I have to calculate the difference right?
I only know this formula: ∆𝑆 = +𝑁𝑘 ln(1/2 ) = −𝑁𝑘 ln(2)
I struggled the whole day with this task, I hope I can solve it with your help
Hi everyone!
It's about the following task:
Calculate the molar entropy of H2O(g) at 25°C and 1 bar.
θrot = 40.1, 20.9K, 13.4K
θvib=5360K, 5160K, 2290K
g0,el = 1
Note for translational part: ln(x!) = x lnx - x
Can you explain me how to calculate this problem?
Hi guys,
Can you give me some feedback on whether my calculation is correct? I applied the formula below (Boltzmann Distribution) but I didn‘t know what to use for the variable z. I don‘t even know if I used the correct equation. Can you help me further?
The task is:
Consider a system of...
I think dU= TdS - PdV + sum of ... dni ?
But what does that equation have to do with the question above? Should we not explain what types of variables X̅ must have? Please apologize, I'm a lil bit confused.
The question is: If X is an extensive state quantity and X̅ is the associated partial quantity, what types of variables must X̅ have?
I think we should explain the properties of partial molar quantities. Which characteristics do they have? We shoul count the different variables of these partial...
And I noticed that I forgot to post all the relevant equations for that task.
The complete task looks like this (see below).
The question d) is false because V and S are not constant, they are not intensive, V and S are extensive properties. Therefore, they can not be considered as constant. Is...
@Chestermiller, thank you so much for your reply. So the answer to that question "If X is an extensive state variable and X̅ is the associated partial variable, what types of variables must X̅ have" is: the variables are T,p, and the mole fraction ni because they are all intensive?
Hi everyone!
It's about the following task.
Partial molar quantities
a) How are partial molar quantities defined in general?
b) If X is an extensive state variable and X̅ is the associated partial variable, what types of variables must X̅ have?
c) Is the chemical potential of component i in a...
Hi everyone!
Do you know why fatty acids burn in the presence of carbon? I found some explanations on the internet but they didn't help me. Can you explain me (in simple terms) why fatty acids burn in the presence of carbon ?
Hi everyone!
Do you have an idea which organs/parts of the body are ONLY functional on glucose?
I would say the brain, pancreas, liver and kidney, but I have to take into account only those organs that are ONLY functional on glucose
