Heat of Condensation: Solving Methanol Homework

AI Thread Summary
The discussion focuses on calculating the heat of condensation for methanol by using the relationship that the heat of condensation is the negative of the heat of vaporization. The user attempted to find the heat of vaporization but struggled to arrive at an answer that matched the provided choices. They confirmed that the process of taking the negative value for condensation is correct, as energy is released during this phase change. Another participant reviewed the user's work and suggested that their answer appears correct. The conversation emphasizes the importance of following forum rules regarding posting images.

Homework Equations



Heat of condensation = -(heat of vaporization)

The Attempt at a Solution



Okay, so I tried to find the heat of vaporization. Then I to took the negative of it since the process is condensation, and energy is being released from the methanol as it condenses into a liquid. I was wondering if my process was right since I tried multiple times, unsuccessfully, to even get an answer that was in the answer choices.

I just skimmed and it looks OK to me. (a) seems to be the right answer.

Please read the forum rules. Don't post questions as images unless it is really necessary.
 
Thank you, and I apologize for the images I've posted. I'll refrain from posting further images but I can't do anything about the images in posts I've already posted.

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...
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...
