Thank you for the resource! Besides the last paragraph, I was familiar with the theory. So the statement of this paper is, that the Activation Energy in Arrhenius corresponds to an Activation Enthalpy in Eyring?
Furthermore, you said
.
So isn't Delta G a "true Energy". I mean it has the unit of...
Hm I cannot see that immediately from the Gibbs Helmholtz relation… could you explain that a little to me?
Further hypothesis is: at low temperatures, the entropical Term in dG = dH - TdS vanishes. But the paper works at Temperatures around 60K, so… everything seems a little vague to me…
Well in the upper left area of the second page, the author uses g(H). I was assuming, that H denotes the Enthalpy here. (I was learning from a non-public script which cites the above article. In the script it was explicitly called "Enthalpy".)
I'm currently taking a Biophysics lecture. There's a vast usage of the terms Enthalpy and Gibbs Free Energy. I understood that most of the time, we're dealing with the Gibbs Free Energy, because our experiment is at constant Temperature (e.g. room temperature) and constant Pressure (e.g. 1 atm)...
Hi Chet,
thanks for your detailed explanation. That gives us exactly the expected result of 5/3 -> f = 3. But what's wrong with my "short" approach?
Thanks!
P.S.: I somehow suspect that this exercise has been created in a "reverse" way which is ambiguous… I mean going back from the Cp/Cv...
In the case of isochoric heating we have ΔW = 0 which gives us from Joule's law and the first law of TD: ΔQ = f/2 n R ΔT.
Furthermore we know from the ideal gas equation, that Δp V = n R ΔT, which we can solve for ΔT = Δp V / (R n).
We insert the latter equation into the first one and get ΔQ =...
Homework Statement
A Gas is in a Volume V0 = 1 Liter at Pressure p0 = 3 bar.
Isochoric Heating using the Heat Q1 = 182 J, the pressure raises to p1 = 6.34 bar.
Gas is reset to inital state. Isobaric Heating using the Heat Q2 = 546 J, the Volume increases to V2 = 3 Liter.
Calculate Cp/CV...
