If I want to find the standard ΔG for a reaction in an electrochemical cell, I can use the equation ΔG° =-nFE° where n is the number of moles transferred, F is Faraday's constant, and E° is the standard emf of the cell. If I know the standard reduction potentials of the redox reactions happening...
Interesting. I was thinking that the formation of oil globules suggests a significant difference in entropy compared to the oil spread evenly sitting on top of the water in a flat layer because the less dense oil must push itself down into the water in order to establish the globule with the...
I just read that when oil is mixed with water, the systems equilibrates so that the surface area of the oil-water interface is minimized. This occurs because the conformation with the lowest surface area is the most energetically favorable, and it is energetically favorable because it introduces...
Thank you for the reply! My conclusion is that there is a small decrease in entropy. When you say "dissolve," I take it to mean that some molecules will leave their own phase and become fully solvated by molecules of the other phase. It follows that at equilibrium, these dissolved molecules can...
I'm rockinrack. I'm currently studying for the medical college admissions test and my physics review book frequently leaves me with unanswered questions. I hope to have some of them answered here, and to help answer other member's questions when my knowledge set can be useful.
Also, science...
My question is: when oil and water from separate containers are poured into the same container and given time to equilibrate, is the entropy change positive, negative, or zero?
I've been told that there is zero change in entropy because the water and oil do not mix at all. However, I suspect...
